Clock

Format: Best of three · stops at two wins
Board: 5 × 5 footprint · 7 layers · one starting layer each
Clock: 60s bank per round · max 10s per turn · match at most 7 min
Openers: You open round 1, bot opens round 2, you open round 3
Opening swap: Once per round, right after the first move, the responder may take over the opening side instead of moving
Opponent: House practice bot — strong, deterministic, runs locally, not a person

Each move climbs exactly one layer toward the enemy, to any of the nine cells above (red) or below (blue).
Straight up or down only into an empty cell. Any of the eight diagonal cells: empty, or capture an enemy piece.
Reach the enemy's outer layer, capture every enemy piece, or leave the opponent with no move to win the round.
Drag to rotate, scroll to zoom, or use the layer slices below the tower. Tap a piece, then a highlighted cell.
