The four suits are: Baba, Fofo, Jiji, Keke.

There are 6 slots in the middle. Four of these slots initially contain stacks of 13 cards.

There are four suit-specific slots on the right.



"- Pile cards of every suit in ascending order on the slots on the right.
- Cards are stacked in the middle slots in descending order.
- You can only pick up a stack of multiple cards if they're of the same suit.
- When you're holding a single card, you can right-click on another card to place the held card sideways on top of the clicked card. Any card can be placed on top of a sideways card, but you can only have 3 sideways cards at maximum at a time.
[Example of a valid stack - from bottom to top:

10 of Fofo (sideways)
4 of Keke
3 of Keke
2 of Jiji]
- To turn a sideways card back upright, you need to pick it up and place it in a valid spot for that specific card.
- Press S to autostack."

"Built from Tap Solitaire with the intention of trying to create a solitaire with Baba Is You -esque rule-changing gameplay. The result is pretty chaotic but maybe that's appropriate?

There are four suits (Baba, Fofo, Jiji, Keke), and ten values (from 1 to 10). The deck also contains 12 special rule cards (see Rules, below): 4 suit rule cards, 4 verb rule cards, and 4 quality rule cards.

There are 5 middle slots. Four of them initially hold stacks of 13 cards.

There are 4 additional empty slots at the top.

There are four suit-specific slots on the right.



"- Pile number cards 1 to 10 of every suit in the 4 rightmost slots.
- The top slots can hold 1 card each normally, and up to 3 if the cards form a rule (see below)
- Number cards are stacked in descending order, but only stacks of matching suit can be moved together.
- There are 3 types of rule cards:
Suit - BABA, FOFO, JIJI, KEKE
Verb - Is
Quality - On Same, Any Suit, Opposite, +5
- Rule cards can be stacked by type.
Rule cards can also stack to form 2 types of 3-card rules:
1: Suit - Verb - Quality (e.g. BABA - IS - +5)
2: Suit - Verb - Suit (e.g. KEKE - IS - JIJI)
- These 3-card rules can be placed in the top slots.
- When a rule exists, it affects the suit mentioned in the rule:
ON SAME: the suit's cards can be placed on any cards of the same suit.
ANY SUIT: the suit's cards behave as if they were of any suit.
OPPOSITE: the suit's card values become their opposites (10 becomes 1 etc.)
+5: the suit's card values increase by 5 (wrapping to 1 after 10).
SUIT 1 IS SUIT 2: the cards of suit 1 temporarily become cards of suit 2.
- Press S to autostack.

NOTE: ANY SUIT doesn't affect stacking onto the top slots."

"Defeat 16 eldritch monsters by matching them up with appropriate cards! Features a special deck with more esoteric suits: Moons, Knives, Books and Candles.

Playable with a standard deck: Yes
Undo: Yes"



There are five slots in the middle. One slot is initially empty. The other slots are initially filled with stacks of 13 cards each.

There are four "monster slots" on the right, and two "attack slots" next to each of the monster slots.

The cards with values 10, 11, 12, 13 are monster cards. All others are number cards.



"- Defeat all 16 monsters by matching them with cards of equal value.
- When a monster card is on the top of one of the 4 middle slots, it'll jump to an open monster slot on the right. If there are no open monster slots available, YOU LOSE.
- Every monster slot has 2 attack slots next to it. When the monster slot is filled, you can place any number card in the attack slots. If the combined value of the 2 cards in the attack slots is equal to the value of the monster card, the monster is defeated and all 3 cards are discarded.
- An ace is normally of value 1, but if it's in an attack slot for a monster of matching suit, its value becomes 7. NOTE: In order to complete the solitaire, you need to use at least 1 ace matching suit with a monster.
- The number cards are stacked and moved in ascending/descending order of alternating suit. The order can change mid-stack, so 4-3-2-3 is a valid stack.

[Example:
Against a monster of suit Knives:
Ace of Candles = 1
Ace of Knives = 7]"

The player starts with a standard deck of 52 cards, with four suits and 13 values from 1 to 13. The four suits correspond to four elements: air, water, earth, fire.

There are six slots in the middle. Initially, two slots are empty, and four slots contain stacks of 13 cards.

There are three empty slots on the right, arranged in a triangle shape.

There is an empty red slot on the right.



"- The deck you're using is a standard 52-card deck. The cards with sun icons are the aces.
- The cards are stacked and moved in ascending/descending order of alternating suit. The order can change mid-stack, so 4-3-2-3 is a valid stack.
- The triangle in the bottom-right corner can be used to combine cards. Place 2 cards in the bottom slots, and you'll get their combination in the top slot. A combined card can't be combined again. Combined cards can be stacked as any suit.
- Your goal is to pile cards from 1 to 26 on the red slot on the right. The suit doesn't matter, only the number value.
- NOTE: You can switch the Roman numerals into Arabic numerals in the settings menu.
[Example:

A blue 5 and a yellow 7 are placed in the two bottom slots of the three-slot triangle; they vanish, and a 12 card appears in the triangle's upper slot.]"

There are 8 slots at the bottom, each initially containing 5 number cards.

There are 8 slots at the top, each initially containing a random number of face cards, face-down.

There are four suit-specific slots on the right.



"- Pile cards of every suit in ascending order from 1 to 10 on the slots on the right.
- Non-face cards are stacked and moved in the bottom slots in either ascending or descending order of alternating suit. The order can change mid-stack, so 4-3-2-3 is a valid stack.
- The face cards are unknown and move from left to right in the top slots based on their suit/value whenever you move a card, wrapping around at the end of the row. Their movement is determined by the cards in the bottom slots:
Jacks: move above the next bottom slot with 0 cards of the Jack's suit, if one exists.
Queens: move above the next bottom slot tied for least cards of the Queen's suit (not 0).
Kings: move above the next bottom slot with at least 1 card of the King's suit, if one exists.

[Example:

Jack of Clubs
Bottom slot 1: Clubs
Bottom slot 2: Clubs
Bottom slot 3: Hearts
Bottom slot 4: Clubs
Jack moves to upper slot 3.

Queen of Clubs
Bottom slot 1: Clubs, Clubs, Clubs
Bottom slot 2: Clubs, Clubs
Bottom slot 3: (empty)

Queen moves to upper slot 4.

King of Clubs
Bottom slot 1: Spades
Bottom slot 2: Clubs
Bottom slot 3: Hearts
Bottom slot 4: Diamonds
King moves to upper slot 2.]

- You need to use the above logic to determine the identity of each face card. When you have a guess, click on a face card and choose the card you believe it to be from the menu that opens.
- When you've filled the slots on the right and have given a guess for each face card, the game ends. If your guesses were correct, you win. If not, YOU LOSE.

There are five slots on the left, four of them initially filled with stacks of 13 cards each.

There are five empty slots on the right.

A scoresheet in the bottom-right keeps track of the hands scored throughout the game so far.



"- Cards are stacked in the slots on the left in descending order.
- A single card can be placed in each of the 5 slots on the right (after this, it can't be removed). Once all 5 slots are full, the cards in them are evaluated as a poker hand. Only the best possible hand is considered, and points are awarded as a sum of the values of the cards that contributed to the hand. If the given hand had already been awarded previously, the score will be updated if the new one scored higher.
- The goal is to accumulate 240 points or more in total. You do not have to get points for each different hand there is as long as the score is high enough.

[Example:
For a combination of:
6 Clubs , 6 Spades , 10 Spades , 7 Diamonds , Q Diamonds
The result is:

The following 8 suits are used: Clubs, Hearts, Spades, Diamonds, Hexagons, Triangles, Pawns, Moons. Hence the entire deck has 104 cards.

There are 5 slots in the middle, each initially holding a stack of 20 cards in random order.

There are 8 slots on the right, one per suit. At the start of the game, the 4 leftmost slots (Clubs, Spades, Hexagons, Pawns) already hold the Ace of the given suit. The other suit-specific slots are empty.

On top of the 8 suit-specific slots, there are three additional empty slots. The topmost one overlaps the Clubs, Spades, Hearts, and Diamonds slots. The middle one overlaps the Spades, Diamonds, Hexagons, and Triangles slots. The bottommost one overlaps the Hexagons, Triangles, Pawns, and Moons slots.



"- Pile cards of every suit in ascending order on the 8 slots on the right.
- Cards are stacked in the middle slots in descending order of alternating suit.
- You can also stack cards of the same value on top of each other, but you can't pick up cards stacked like this together.
- There are 3 slots on the right that can hold 1 card each. While one of these slots is holding a card, the suit-specific slots underneath can't be used.

There are just two card types: face-up, face-down.

There are four slots in the middle, each initially containing: 1, 2, 3, and 4 cards. Above each slot, an image of the "next card" is displayed.

The deck of cards is displayed on the left, and the total count of both types of cards in the deck is displayed beneath.

Three slots are on the right, each initially empty and marked with the number "5".



"- The deck consists of 104 cards: 52 face-up and 52 face-down. Think of these as 2 suits.
- Cards of the same suit join into a single group when stacked. You can't move a card without moving its entire group.
[Example:

1 face-up card + group of 2 face-up cards = group of 3 face-up cards]
- Groups can be picked up from anywhere (even under other groups), but only placed on empty slots or groups of size 1 higher or lower. You can place a group on another group regardless of their suits.
- The goal is to place groups of cards on the 3 slots on the right so that the size of a group is higher or equal to the number next to the slot.
- Each of the 3 slots requires first 5, then 7, then 9 and finally 11 cards. The groups can be of either suit.
- Clicking on the deck deals a new card on all 4 middle slots. You can see the upcoming cards above the slots.
NOTE: fulfilling the goal requires 96 cards at minimum, so you have a surplus of 8 cards at the start."

The deck consists of 112 identical cards.

There are four middle slots, each initially containing a random number of cards organized randomly into groups. There is an extra slot on the right.



"- All cards are identical, but they're placed into groups; the number of cards in a group determines the group's value.
- You can stack and move stacks of card groups in descending or ascending order of value. The ascension/descension direction may change mid-stack, so 4-3-2-3 is a valid stack.
- You can combine two groups by right-clicking one while holding the other as long as their values differ by 1 or less.
- A group on an invalid spot (ie, on another group so that their values aren't in descending/ascending order) is highlighted in red. You can't place groups on an invalid group, or combine with one.
- Your goal is to fill all 4 slots with groups in descending order from 7 to 1. Once you do this, the slot locks up and can no longer be used.

This game uses special cards. There are 8 suits, each corresponding to a specific planet (Neptune, Uranus, Saturn, Jupiter, Mars, Earth, Venus, Mercury.) Each card has a suit and "aspect" (a secondary suit, different from the primary one). There's a card for each combination of suit and aspect, for a total of 56 cards.

There are 8 slots, one per planet. Each slot initially holds a stack of 7 cards.

The 8 planets are initially all at the same height. Throughout the game, each planet can move between three different heights ("orbits").



"- Pile cards of every suit on their corresponding planet.
- Cards that share the same suit (middle symbol) can be stacked. Every card also has an aspect (top symbol) which denotes an additional suit that the card can be stacked on.
- You can only pick up a stack of multiple cards if they share the same suit.
- Whenever a card is moved, the two planets corresponding to the card's suit and aspect advance their orbit. Each planet has 3 orbit levels, which it rotates through as its orbit advances.
- Cards can only be moved between planets with the same orbit level, unless one of the planets has 0 cards. Cards can be placed on planets with 0 cards from anywhere."

Undo: Yes"



This game uses special cards. Each card has two sides (red and blue), and each side has its own value, from 1 to 5. The deck has 25 cards, one for each possible combination of values on both sides.

There are five slots, each initially holding a stack of 5 cards.



"- Fill the slots with 5 stacks in descending order with alternating color.
- You can pick up a stack of multiple cards if they adhere to the rule above.
- At any time, you can right-click to turn over the top-most card of a stack."

"In this solitaire you'll have to solve a murder case while also stacking cards! Who's the killer, what's the killing weapon?
DIFFICULTY: ****-
Playable with a standard deck: No
Undo: Yes"



There are five slots in the middle. One is initially empty, and the other four contain card stacks of random length, with a total of 51 cards. Only the topmost card in each stack is initially face-up. The face cards have red backs while the other cards have white backs.

There are four empty slots at the top.



"- Your task is to figure out who killed [the victim] at the party and with what. Both the killer and the weapon are cards in the deck.
- Each 10 and face card is a party guest (for a total of 19 guests, discounting the victim), and every other card is a potential murder weapon or method. Hover over each card to see its name.
- Each time a guest is revealed, they're questioned and their response appears on the right edge of the screen. However, 2 guests have no idea what happened, and 4 other guests give an incorrect account of the events, 2 about the murder weapon and 2 about the killer.
- Some responses claim that the killer or murder weapon is in a particular stack; in such cases all cards in that stack get marked with a number indicating which response relates to them.
- You can use the 4 buttons next to every response to keep track of whether you think they're true or false.
- Once you think you know the identities of the killer and the weapon used in the deed, press the 'I Know!' button.
- You can place cards on each other as long as their values differ by exactly 1, no matter what their suits.
- You can pick up a stack of any size as long as all the cards are in descending order. Aces are counted as 1 in all situations.
- At the top of the screen are 4 slots that can hold 1 card each."

"A solitaire where the cards form an electric circuit; manage the circuitry to avoid getting stuck.
DIFFICULTY: ***--
Playable with a standard deck: Yes, although you may want to draw on the cards
Undo: Yes"



The playfield is a grid of 48 slots, with 6 rows and 8 columns. Each slot initially holds a random card. There are four additional slots off each corner of the grid, each initially holding a King. Each card has between one to four circuit lines, branching out from the card's middle to its four sides.

There are four suit-specific slots on the right.

An indicator of "Electricity left" is in the bottom right. Initially, the player has 3 electricity units.



"- Pile cards from 1 to 12 of every suit in ascending order on the slots on the right.
- All cards have circuit lines on them. The Kings of each suit act as power sources, and power propagates through the card grid along the circuit lines.
- You can pick any card except a King and place it anywhere; placing it onto another card makes it swap places with that card. Kings cannot be swapped with.
- Picking or placing an unpowered card makes you run out of electricity, as does placing a card on an empty grid slot. Placing a card onto the slots on the right regains 1 electricity, and you need 3 electricity to pick or place an unpowered card again (or place a card on an empty grid slot).
- (The deal guarantees that the two topmost Kings power at least one card.)"

"Most cards in this solitaire start out without a suit or number. Your task is to resolve each card without running into impossibilities.
DIFFICULTY: ***--
Playable with a standard deck: No, emphatically
Undo: No"



As noted in the rules, each card initially has no specific suit or value, except for the four 2-cards. There are 54 cards in total.

There are three middle slots, each initially holding a stack of 18 cards.

There are four suit-specific slots on the right.



"- Pile cards of every suit in ascending order on the slots on the right.
- You can stack cards and move the stacks in descending order of alternating suit.
- At the start of the game, all cards except the 2-cards are ambiguous - they are simultaneously of all suits and all remaining values. Picking up stacks of cards and moving them under other cards limits their options based on the above stacking rules, and once a card has only one possible identity, it'll transform into that card.
- Cards can be moved into positions where they no longer have any possible options for their identity; in these cases, they become impossible cards and can no longer be placed on the slots on the right. There are 54 cards in the deck, so a maximum of 2 cards can become impossible without it preventing you from solving the deal.
- A card can be placed on the slots on the right as soon as it has a value, even if it didn't yet have a specific suit. However, the card must still have the required suit of that slot in its possible options.
- Hover over a card to see its name and the information it has about its identity relative to other cards."

"Most of the stacks are locked down! You'll need to unlock them by keeping cards in specified holding slots to gain access.

There are four slots, one above the other, each initially containing a stack of 13 cards. Each of the four slots also has some additional 1-card slots next to them, as follows:
- Slot 1: one 1-card slot
- Slot 2: one 1-card slot; a key icon
- Slot 3: two 1-card slots; a key icon
- Slot 4: three 1-card slots; a key icon

Four suit-specific slots are on the left.



"- Pile cards of every suit in ascending order on the slots on the left.
- You can stack cards and move the stacks in descending order of alternating suit.
- The 3 slots with keys next to them are locked slots. In order to gain access to them, the holding slots to the left of them need to be filled - each of them can hold exactly 1 card. You can click on a filled holding slot while holding a single card to swap the two cards.
- At the top there's also one normal slot that is not locked, and a single-card holding slot to the left of it.
- Press S to autostack. Note that the autostacking will not take cards from holding slots to prevent making the deal impossible to solve."

"A solitaire based on the classic Wolf-Sheep-Cabbage riddle. Can you get all the cards safely across the river?
Designed and implemented by Hazelstorm
DIFFICULTY: ***--
Playable with a standard deck: Yes
Undo: Yes"



There are three suits: Carrots, Rabbits, Ferrets.

The playfield is separated into two river sides. A cute little boatman in the middle symbolizes which side the player is currently on. The player starts on the left side.

Both sides of the river have three slots. The three slots on the left initially contain stacks of 13 cards each. The three slots on the right are initially empty.

Counters at the bottom indicate the number of cards in each suit on either side.



"- Move all cards across the river to win.
- You can pile and move card stacks in descending (not necessarily consecutive) order and alternating suit.
- You can only take card stacks from the side of the river you're currently on. The boat indicates the side you're on.
- When you move a card stack across the river, you will move to the same side as you moved the stack to.
- You lose the game if there are ever 2+ more Ferrets than Rabbits on the same side of the river while there's at least 1 Rabbit on that side!
- You lose the game if there are ever 2+ more Rabbits than Carrots on the same side of the river while there's at least 1 Carrot on that side!"
