In Brikks, the active player rolls two dice. The two dice determine which specific "quadromino" (piece) that 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. If you cover a circle on the grid that`s the same color as the quadromino just placed there, you collect two energy points. By spending one energy point on a turn, you can possibly "rotate" the quadromino to be placed depending on what dice were rolled; by spending five energy points, you can place exactly the quadromino you want, ignoring the result of the dice. As soon as you can no longer place a quadromino in your grid, your game is over.

Once everyone has filled their grid to the top, tally your points. You score 1-5 points for each horizontal line that contains 8-10 Xs, with these line points doubling, or even quadrupling, as you go higher in the grid. There are several other ways to gain points. Whoever scores the most points wins! Brikks also contains rules for a duel mode and a solitaire mode.
