Offline Chess Puzzles & Vision

50,000 offline puzzles, mate in 1 to 5+, board vision drills and a coach that says why a move is wrong.

What it does

Chess puzzles that work on a plane, on the subway or in a basement. The whole library of 50,000 rated positions from real games is on your phone, with no account and no waiting for a server. When you miss, the coach says what happened and names the idea behind the right move, such as a fork, a pin or a back-rank mate.

Highlights

  • Why a move is wrong: not just a red cross, but what your move allowed
  • Fast-settling rating: your first ten puzzles move the rating faster, then puzzles are picked around it; failed ones return later
  • Board vision: find and name squares, light or dark, knight routes, blindfold coordinates and piece vision, on a twelve-level path
  • Many modes: all puzzles, puzzle of the day, puzzle streak, puzzle rush, mate trainer (mate in 1 to 5+), endgame studies and chess classics
  • Progress in plain numbers: a rating per tactical motif, a heat map of missed squares and a streak that forgives one missed day
  • Your look: dark, light and AMOLED themes with board and piece styles

Made for

  • Short offline training sessions on a commute or a flight
  • Players who want to learn patterns instead of memorizing one move
  • Anyone who wants to practice board coordinates and visualization

Frequently asked questions

Can I train with chess puzzles offline?
Yes. After install nothing needs the internet. The library is packed inside the app and unpacks in the background on first launch; the first puzzles unpack right away so you can start at once.
Do I need an account?
No. There is no sign-in anywhere.
Are these puzzles for beginners?
Yes. Your rating settles within about ten puzzles, and each puzzle is picked close to it, so a new player does not get master-level positions.
How is a puzzle rated?
Each position carries a rating taken from real attempts on it. Your own rating is updated the Elo way after every solve or miss.
Is it free?
The free version shows ads. Pro removes the ads with a single purchase, no subscription.
Where do the puzzles come from?
From an open CC0 database of positions from real games.
