Brikks can be viewed as tabletop Tetris, with each player trying to place falling blocks into their grid to score the most points.
To start the game, each player draws a different quadromino at the bottom of their individual game sheet. On a turn, the active player rolls two dice — a colored d6 and a numbered d4 — then optionally rolls both dice again. The two dice determine which specific quadromino — that is, which colored shape and in which orientation — all players must "drop" into their grid. To represent this, you draw an outline of the block at the bottom of your sheet as if you had dropped it in from the top, then X out the spaces covered by the quadromino.
