Chesspy

Place chess pieces. Hit every number.

Numbered squares are targets. Place chess pieces so each target is attacked by exactly its number — in the app, your pieces are called agents. A 0 is a safe square: nothing may attack it. Match every number and the next board is right there.

Every board has exactly one solution, and you can reach it by logic alone — no guessing.

Today’s Mission
• Twenty boards in a row, growing from 3×3 to 6×6.
• Three hearts. Placing or moving an agent so a number newly turns red costs one heart. Removing and undoing are always free.
• Lose your last heart and you can see that board’s answer.
• Everyone gets the same mission each day. Finish it to see your Top % today.
• Sundays bring the S-Rank Mission: it starts at 4×4 and the last five boards are 7×7.

Battles
• Create a battle and get a six-digit code. Paste the link in a group chat and friends jump straight in.
• Everyone plays the same five boards with three hearts. Most boards, then fewest hearts lost, then fastest time wins.
• Up to 16 players, each joining as a chess piece: king, queen, rooks, bishops, knights and pawns.
• A battle stays open for 7 days. Joining is free for anyone.

The agents
• The rook attacks along rows and columns, the bishop along diagonals — all the way to the edge, right past other agents.
• From board 10 the knight joins in, jumping in an L.
• No chess needed. A four-board tutorial shows you how on the board.
