An ambit is the set of squares a chess piece can move to.
Build the puzzle's YELLOW footprint with ambits — exactly. No spillover.
1
Pick a piece. Tap a Rook, Knight, Bishop, Queen or King in the rack.
2
Place it. Drop it on any empty square — color doesn't matter. Its ambit lights up.
3
Match the footprint. Tap Check to overlay the combined GREEN ambit of every piece. Win when green covers yellow exactly.
Spillover → lost life
If any ambit square lands outside the yellow footprint, you lose a life. UNDO rewinds your last piece — but a life you've already lost stays lost.
Medals
- Win with 0 UNDOs → 🥇 Gold
- Win with 1 UNDO → 🥈 Silver
- Win with 2+ UNDOs → 🥉 Bronze
The puzzle ends when…
- Green ambit equals the yellow footprint — victory.
- You run out of lives.
Pro tips
- Ambits don't block each other — only their union matters. Pieces can sit anywhere.
- Solve corners and isolated cells first — they constrain piece choice.
- Knights reach awkward L-shapes; bishops cover long diagonals; the queen is overkill (and easy to spill).
- Hit Check often. Cheap to peek, expensive to spill.
