In each round, players lay out a number of polyomino cards in a circle, then place the rabbit between two cards. On a turn, someone rolls the die, moves the rabbit forward, then removes the card indicated by the rabbit. Each player must draw the polyomino indicated on this card in their grid. Once a certain number of cards have been played, the round ends, players score points, then you lay out more cards for the next round.
Each player has four special actions available to them during the game: You can choose to draw the card before or after the chosen card, you can cut a polyomino into two pieces before adding one piece to your grid, you can fill in a 1×1 space in your grid, and you can do one of the above actions a second time. When you take one of these actions, you mark it off as each can be used only once (except for the one you use a second time, if you know what I mean).
You lose a point for each space that you don’t cover, so try to pack everything in as tightly as possible!
