Tile every square: each one must hold a piece or sit in some piece's line of sight.
Pieces can only stand on clean squares — rubble must be tiled but can't be built on.
In a run every unspent piece carries over, and a BOSS board arrives every few rounds;
its pieces come rounds early, so overspending now is what kills you later.
PAR is the proven cheapest tiling. Most cheapest tilings are prisms, imps and pikes;
on tight boards start from the square that the fewest pads can reach.
Drag placed pieces to move them; right-click or long-press to take one back.
