How to play

Roll. Stack. Shatter.

Each player has a 3 by 3 board. Take turns rolling and placing dice. The highest score wins.

  1. Roll

    Roll a die, 1 through 6.

  2. Stack

    Place it in a column on your board. Dice stack from the bottom.

  3. Shatter

    Matching faces in the same column on their board are destroyed.

  4. Score

    Matching dice in a column multiply: a single scores once, a double scores four times, a triple nine times.

5 pts
One 5 ×1
20 pts
Two 5s ×4
45 pts

The game ends when a board is full, and the highest score wins.
