Quad Pro Quo is a card game that basically compares the value of one side of a card against the other to take over the other card. Winning condition is simple, own more cards than the opponent when the board is filled.

The game basically has similar tricks with final fantasy 7 Triple Triad, but instead one number for each side, it is two numbers, and the board is 5x5 instead 3x3. Considering that I was an avid fan of triple triad back years ago, I still have a few strategies from it that I found to be working on Quad Pro Quo and would love to share some.

1. All Around
Examples:
66
66
All around cards are cards that have almost similar values on all sides. High value all around mainly useful for tapping two cards or more at once, but also can provide a very strong defense. Please note that low value all around is the opposites, they are very weak and allow the card to be flipped four times.

2. Diagonal
Examples
63 63
27 36

Considering attacking and defending in Quad Pro counts two numbers at once, Cross-Section is the best defense card after all around. They usually hard to attack due to the low numbers but also hard for opponents to take because of the high numbers part. I usually have 1-2 of this kind of cards on deck as long as they do not have two '2' or '1'.

3. Two sides
Examples:
66 24
33 76

Two sides seemingly have only one power side, that useful to attack other cards. Defense wise, two sides can defend from three sides, except on the weak side. These cards are useful for defensive but I found them hard to attack due to positioning.

4. Three sides
Examples:
26 36
66 76

Three sides are basically a card that is powerful to attack from three directions and have defenses on all sides. They are a powerhouse and a must have.

Ideally, filling the deck with the highest numbers or all three sides would be beneficial in this game, but player starts with mostly weak cards except for three heroes card. In that case, I have several tips to start:

1. Bring all the heroes card.
2. Make sure to pick cards that are diagonal in power, or have the number 7 on them.
3. Make sure to have at least one bait card that can be easily taken by yourself from TWO sides.
4. Make sure to bring all elements. Having a balance in element might be good in general until you have studied what kind of element cards the specific opponent brings.

Strategy:
- If you start first, place a bait card in a single wall of the board, preferably near a corner. This means, when the opponent takes the card, you can flip it back and secures it from further flipping. If in any chance opponent let you put your card in the corner, it is most likely you can secure two cards at once.
- If you start the second, consider how much 'attackable' sides the opponent put. If it is two or three, it is best to secure your own card instead. Like putting a card in the corner with a big number facing outward that corner.
- You only need to have one more card than the opponent to win, so playing defensive might worth it in the long run. Playing aggressive might opens two or more of your cards to be attacked at once.
- Keep your best three or all around card for the last hand.
- On advanced strategy, you can prepare multiple baits to make opponents lock themselves and allow you to take two or more cards at once.
- Elements can increase your cards attack, but I honestly won't rely on it.

This is all tips and tricks I have for now. If I found a new mechanic in the card game or new trick to win, I would add so. Lastly, I apologize for my limited English, and have fun playing The Tenth Line!
