Objective: Match the YELLOW/ORANGE puzzle footprint by placing chess pieces so their ambits (the squares they can move to) combine to cover it exactly.

1. Select a piece from the rack.
2. Place it on any EMPTY square of ANY colour.
3. Tap Check to see the green combined ambit of all pieces you’ve placed so far.
4. If an ambit square spills outside the footprint, you lose a life. UNDO can’t undo a life you’ve already lost.
5. You can tap UNDO to remove the last piece you placed. This rewinds the ambit and lets you try a different idea.
6. When the green ambit perfectly matches the yellow/orange footprint, you win.

Tip: Ambits don’t block each other. Pieces can be anywhere as long as their ambits stay within the footprint.

Medals:

• Win with 0 UNDOs → 🥇 Gold
• Win with 1 UNDO → 🥈 Silver
• Win with 2+ UNDOs → 🥉 Bronze

The timer still runs for fun & bragging rights, but medals depend only on UNDOs used.
