Logic puzzles that teach chess
Free · In‑App Purchases
Catch Rocco and the Masked Bandits! Every animal witness sees like a chess piece. Solve the mystery, learn how chess pieces move. A new free Daily Case every day.
Somebody raided Farmer Fern's cookie jar! Rocco and the Masked Bandits are hiding in the garden, and Detective Barkley needs your help to find every last one.
Checkmutt is a logic puzzle for kids ages 7 and up. It's like Minesweeper meets chess, with animal detectives.
HOW IT WORKS
Each animal witness shows a number: how many bandits it can sense. And each animal senses the garden the way a chess piece moves:
• Detective Barkley the Mutt moves like a King
• Whiskers the Cat moves like a Rook
• Professor Hoot the Owl moves like a Bishop
• Hopper the Frog moves like a Knight
• Peep the Chick moves like a Pawn
• Queen Bea moves like a Queen
Tap an animal to light up what it sees, mark where the bandits hide, and tap Check. Catch them all and the raccoons pop out of hiding: Checkmutt!
EVERY CASE CAN BE SOLVED WITH LOGIC
No guessing, ever. Stuck? Tap Hint and Barkley explains the next step in plain, friendly words.
