Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Pure logic. Zero luck. Master the ultimate deductive brain teaser that combines the spatial strategy of chess with pure process of elimination.
The board is populated. One piece is the secret Target. Your mission? Deduce the exact piece in the fewest moves possible. Apply clever clues to the board based on chess mechanics—Is it on a dark square? Is it a Major piece? Is it being attacked by the White Knight?—and watch as the impossible candidates disappear into the void.
