Chess brain games: memory, vision and speed
Chess brain games are short tests played on a real chessboard. Each one measures one thing: how many squares you can remember, how fast you find a square or a check, how far you can follow moves once the pieces are hidden. A run takes a minute or two, needs no signup and ends on one number.
Beside them sit brain tests that need no chess at all: a reaction time test, the Queens game and a card matching memory game. Each one points to its chess version when you finish.
How your score is ranked
Every result lands on a curve of how players do on that game. Four tiers sit at the same place in every game: Club 1500 is the top quarter, Expert 2000 the top tenth, Master 2300 the top twentieth and GM the top 1%. Blunder Crash is the exception, ranked on its leaderboard only.
A tier names a strength, not a rating. To work out a rating from your game results, use the Elo calculator.

Questions
Are these chess brain games free?
Yes. Every game is free to play with no signup. Signing in saves your runs and puts your bests on the leaderboards.
How is my percentile computed?
Your score is placed on the game's distribution of results, which gives the share of players you beat. Until there are enough real runs, each distribution is modeled from simulated players of every strength on the game's real levels.
Is this like Human Benchmark?
It follows the same idea: short tests that each give one number and a percentile. Most of these are played on a chessboard and ranked against chess strength tiers, and the brain tests that need no chess each lead to a chess version.
Do brain games make you better at chess?
They train parts of the game on their own: board vision, memory for positions, calculation without moving the pieces. They work best as a warm-up next to playing and reviewing your own games, not in place of it.
