How to play Tunnel Caps
An original solo connected-tunnel puzzle with three hand tiles and a finite deck. All touching edges must match and every tile must join an existing open passage. Seal all exits to win; an empty deck and no legal orientation ends the game.
Controls
- Choose and rotate a tile, then select a legal board cell.
- Arrows move grid focus; Enter or Space places; R or Shift+R rotates.
Tips
- Branches add exits, so leave room for caps.
- Discard one tile only when no hand tile can fit in any orientation.
