Game review
How scores work
Move labels
Each move is compared with the engine's best move. The label depends on how much of your winning chance the move gave away: a small slip is an inaccuracy, a bigger one a mistake, and a game-changing one a blunder. A miss means you passed up a chance after your opponent erred. Great and brilliant moves are rare: the only good move, or a sacrifice that works.
Accuracy
A 0 to 100 score for how close your moves were to the best ones. It uses the same formula Lichess publishes, so numbers are comparable with Lichess.
Rough rating
An estimate of the strength your moves showed in this one game. It is a guide, not an official rating, and short games swing it a lot.
Review depth
Fast checks each position briefly. Balanced is a good default. Deep takes a few times longer and is the most reliable. Every flagged move is checked a second time at higher depth before it is labelled. All analysis runs on your device.
