About MindSprint

MindSprint is a set of quick brain games — reaction time, number and sequence memory, the chimp test, mental math, aim, and typing speed — plus a daily Sprint: three games, ninety seconds, one score to compare with players around the world.

How scoring works

Each game produces a raw result (milliseconds, digits remembered, words per minute, and so on). We map that onto a common 0–3,333 scale per game so different skills can be combined, then sum your three daily games into a single Sprint Score. Your long-run Mind Rating moves up or down based on how your Sprints compare over time, and places you in a league from Bronze to Grandmaster.

Free to play

Every game is free, runs in your browser, and needs no sign-up. MindSprint is supported by ads. See our Privacy Policy for how data is handled.
