Free brain training games you can play right now
Eleven original mini-games across memory, attention, reaction and logic. Each one has 8 difficulty levels, and every score is recomputed on the server so the leaderboard means something.
What you can play here
Every level is an original mini-game built around one cognitive task: remembering a sequence of icons, tapping the numbers of a Schulte grid, reacting to a colour change, making 24 from four cards, tracking an N-back sequence, sorting beans into single-kind boxes, tapping tiles before they fade, solving sudoku, and recalling the positions of blocks that have already vanished.
Difficulty never hides behind a mystery multiplier. It changes one thing you can explain: the side of the grid, the length of a sequence, the number of categories, the size of the board. You can read the exact parameters and time thresholds for all eight levels on each game page.
How it works
Pick a level and press start. Each set opens with a 3-second countdown that does not count towards your score. Difficulty 1 is unlocked from the start; clearing a difficulty unlocks the next one, and progress is never taken away.
The browser reports raw numbers only — how long you took, how many you got right — and the server recomputes your score with the same formula it publishes. If the two disagree, the score is rejected. Puzzles are generated from a per-session token, so the server can replay them and check what you actually did.
An honest note on brain training
These games train the task in front of you. Research supports that kind of near transfer — you get measurably better at similar memory and attention tasks — but there is no convincing evidence that brain training raises intelligence or transfers to everyday life. A 2010 Nature study with 11,430 participants found no transfer to untrained tasks, and the US FTC ruled in 2016 that Lumosity’s claims about improving school performance and preventing dementia were unsupported.
So we do not promise that you will get smarter, and we make no medical claims of any kind. What we do offer is a set of well-made games with published scoring, so you can measure your own progress honestly.
