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 three-board tutorial shows you how on the board. More to play • Unlimited: opens after today’s mission. Endless boards that grow to 7×7 — two free runs a day. • Hints: stuck in Unlimited or a past mission? Get the reason for the next move, one step at a time. One free hint a day. • Past missions: anyone can play one past day for free. • Streaks, six achievements that unlock agent designs, and a result card to share. • Dark mode and a colour-blind palette. • English, Korean, Japanese, Traditional Chinese, French, German and Spanish. Pro (one-time purchase) • Unlimited, with no daily limit • Hints, with no daily limit • Create battles • Every past mission — fill a missed day to keep your streak • Every agent design and detailed stats • Pro never touches a daily score, and Today’s Mission has no hints. Everyone plays by the same rules. No ads. No account. Your records stay on your device; Top % and battles use only a random ID with no name.
