Knucklebones online

Knucklebones is a standalone fan recreation of the iconic dice mini-game from Cult of the Lamb (2022, Massive Monster). All credit for the original game design goes to Massive Monster and Devolver Digital.

How to play

Each turn, a die is rolled automatically. Click one of the three columns to place it — the die will fill the nearest free cell to the center.

Destroying Dice

If your die matches the value of your opponent's dice in the same column, their dice are removed. Use this to break apart their scoring combinations.

Points per Column

Matching dice in a column multiply your score. The more matches, the bigger the reward:

• One die with value 4 gives 4 points
• Two dice with value 4 give 16 points
• Three dice with value 4 give 32 points

Two matching dice are highlighted in yellow, three — in blue.

Winning

The game ends when one player fills all 9 cells. The player with the most points wins.
