Rule 01
The 5-Checker Cap
No point may hold more than five checkers.
At no point during play may a single point on the board hold more than five checkers of the same color. A point occupied by five checkers is considered sealed — a sixth checker of the same color may never land there.
This rule breaks the traditional stalemate of stacked prime positions. It forces distribution, rewards forward motion, and turns defensive turtling into an impossibility.
If a legal move would place a sixth checker on a point, that move is forbidden. The player must select a different legal move. If no legal move exists that respects the cap, the turn is forfeit.
