Objective: Cooperatively remove marbles by jumping over them until only one piece remains.
How to Play:
Each board is one of 7 random shapes, with random placement of marbles. Click any marble to select it — it turns yellow, and all valid moves highlight in green. Click a valid spot to jump over an adjacent marble. Marbles only move up/down and left/right, not diagonally. You earn points for each marble you jump and remove.
| Marble | Description | Points |
|---|---|---|
| A basic marble | 10 | |
| Another player’s current marble | 15 | |
| A marble that requires multiple jumps to erode | 5 per jump | |
| A bonus marble — capturing it lets you place a marble anywhere on the board | 30 |
Multiplier Bonus — increase the point value of a jump by continuing from your currently selected marble.
Joining connects you to the live board and claims your spot — jump in whenever you’re ready.
