Shake Shake is a board game using three-dimensional tetromino blocks.
On a turn, place one of your blocks onto the playing area, keeping in mind that the circular plate will shake once you're finished, so you need to place it with care. Blocks must be placed to fill the bottom row first; if you don't have a block to fill the bottom row, you can place a block on the top row. If the next player can fill this empty space, they must do so. If one or more blocks tumble off the plate on your turn, set them aside next to you.
The game ends one of two ways: Either a player knocks off three or more blocks at once, or everyone has placed all of their blocks. In either case, score points to see who wins. To do so, view the tower from above and count the number of blocks in your color that are visible, then subtract 1 point for each dropped block in your possession. The player with the most points wins.
