Here's a reference cheat sheet:
Tetris style 4x4 column grid area
Start of a round
Draw 7 cards (no peeking or free flips)
Market of 3 pairs of cards (faceup)
Actions:
Flip, Play, Buy, Discard:
Flip your hand over once per round.
Play a faceup card from your hand to any column.
Buy a pair from the market (costs 1, 2, or 3 facedown cards from hand) and play the connected pair to any column(s).
Discard any facedown cards from hand freely.
If your cards in grid create a pattern of 4+ (Same suit, rank, or a run in series) discard them from your grid, score it and gain a bonus: suit set is 1 point and no bonus, run set is 1 point and a remove bonus (a faceup card from grid back to your hand), and a rank set is 2 points and a remove bonus.
Cards always slide down to the bottom most position of a column.
Any left over market cards at the end of a round are placed facedown in your grid (horizontally adjacent to one another) to a column of your choice matching the rank of one of the cards in that pair (numbers wrap back around to the left, ie. column 1 is also column 5). If at any point there is a row of 4 facedown cards in your grid, discard those 4 from the grid.
Game end: If you place a card in a 5th row, you lose. If the grid is cleared at the end of a round, you win. If the game lasts all 8 rounds, score 1 point per card in your score pile and lose points for cards remaining in your grid (-1 per faceup and -2 per facedown)
