Learn Othello,
one move at a time.
Most Reversi apps just beat you. This one shows you why you lost — with a difficulty ladder that actually fits, hints while you play, and a review that names every mistake.
In testing now. iPhone, iPad and Android.

Built to teach, not just to win
The engine runs on your device — no account, no sign-in, and it works on a plane.
60 levels that actually differ
Every rung was calibrated by match play against the one below it, so moving up is a real step — from a gentle opening partner to an engine that reads the endgame exactly.
Hints that arrive instantly
The suggestion for your turn is computed while you think, so tapping Hint is immediate — and it marks the square rather than just naming it.
Review every game
An accuracy score, and each of your moves graded: inaccuracy, mistake or blunder, with the move you should have played and the reason it was better.
90 lessons, 15 courses
From the rules and notation through mobility, edges, parity and endgame counting — each lesson played out on a real board, not read from a page.
Puzzles and a glossary
69 puzzles drilled with spaced repetition, and 53 Othello terms explained with a diagram for each — wedge, wing, quiet move, parity.
