Sir Bishop is a focused chess puzzle app built around one satisfying goal: find the checkmate.

300 selected mate-in-N puzzles, from quick mate-in-2 tactics to deep mate-in-5 combinations. Every puzzle is curated, so each one teaches a clean, beautiful idea.

PLAY YOUR WAY

• Auto mode: the app plays the defender, so you focus purely on the mating combination.
• Manual mode: play both sides yourself and work through the defense.

COMPOSE AND SHARE

• Build your own chess positions and puzzles right in the composer.
• Share any puzzle with a friend through a link.
• Save favorites and your own creations to Bookmarks and return anytime.

MADE TO LOOK GOOD

• Three board themes: Wood, Black & White, and Teal.
• Clean, distraction-free design, with hints when you want a nudge.
• Track your progress with a weekly streak.

Start free in Bishop mode, then unlock more puzzles, the composer, and bookmark slots with Rook, Queen, or King.

No accounts. Plays offline. Just you and the board.
