The honest two-player MVP
This page implements the standard 121-hole star for two opposite players, not a six-player tournament. Each side starts with ten marbles and wins only after all ten reach the opposite camp.
Steps and chained jumps
A marble may step to one adjacent empty hole, or jump an occupied neighbor into the empty hole directly beyond it. Additional legal jumps can continue in the same move; jumped marbles are never captured.
Local play and three AI levels
Local mode alternates two people on one device. Easy samples a legal move, Medium favors forward moves, and Hard chooses the strongest deterministic progress score. The labels describe this bounded search, not human skill ratings.
Phone and keyboard controls
Select a marble, then a highlighted destination. Every hole is a labeled button with a visible focus state; touch and keyboard activation use the same legal-move validator. Hint and undo never change the public rules.
Chinese Checkers FAQ
- Is this the full six-player version?
- No. This transparent MVP uses the standard board with two opposite ten-marble sides.
- Can jumps be chained?
- Yes. A move may continue through legal occupied-neighbor jumps to empty landing holes, without capturing any marble.
- How do the AI levels differ?
- All use legal moves. Easy samples deterministically, Medium prioritizes progress, and Hard uses the strongest bounded progress score.
- Can two people share a phone?
- Yes. Local mode alternates turns on one device and uses large labeled controls.
