Othello Analysis Lab

Common wisdom, checked against the numbers

Othello endgames are a game a computer can solve completely, right to the last disc. Game Dojo runs its own Othello solver (negamax + alpha-beta, exact endgame solve), so for any position we can compute exactly how many discs the mover finishes ahead or behind with best play by both sides.

In this lab we take well-worn principles and check them against real positions our solver actually solved, showing the final disc margin of every legal move. Every number is a real result, not a guess.

While you play: In the Othello dojo, an engine evaluates the position in front of you. It is not reading to the end of the game, so treat it as a guide.
In the Analysis Lab: The disc margins here come from solving the endgame to the very last move. They are the final margin with best play from both sides — not an estimate.
