The combination card discard can be shuffled in to a new draw pile. If you run out of parasol tiles then play by house rules. One option is to reset the board and tiles, another is to end the game there. In my testing with 3-4 players, tiles generally don't run out unless one or more players are playing specifically to sabotage. Haven't tested enough in 2 player games however so I can't say whether it's likely to happen there. I'll be revising the rules after more 2 player testing once I get to overhauling the game.

What do you do if you exhaust the entire container?

The tile stacks are actually not infinite, there are only 5 of each colour available and the GAME SETUP rule sheet and the first answer above outlines how many to shuffle in to the container.

4 Players = All tiles (5 per colour > 25 tiles).
3 Players = 4 tiles of each colour (20 tiles).
2 Players = 3 tiles of each colour (15 tiles).

Hi Trefc, thank you for playtesting my game and for the questions, as users not understanding the rules speaks for room for improvement.

How many Parasol tiles go in the container? - This depends on the amount of players you're playing with as outline on the GAME SETUP rulesheet. 5 tiles of each colour for 4 players, 4 for 3 players, 3 for 2. This is to ensure there is always a valid play available since you also remove playing fields based on the amount of players.

What points? - A scoring set scores 5 points, but for each excess tile that doesn't belong to the set (all tiles beyond the three top most tiles) subtract one point per tile down to a minimum of zero. This means that if a pile contains 5 tiles, you score for your matching 3 > 5 points, but subtract 2 from your total and advance 3 steps on the score track.

In the section "Place the parasol tiles in a container than lets you shuffle and draw them at rando, but remove one tile of each colour per missing player below four." You never mention how many tiles youre supposed to start with. since your tile stacks are infinite, how do we know when to start or stop? And then beneath the player counts you denote 5x, 4x, and 3x, which seems contradictory to you said 1 color, Per player missing below four, which would make these x's 1 too high. Something is missing explanation here.

another rule mentions subtract 1 point per excess tile. What points? Where did these points come from? You hadn't mentioning anything about it.
