Every free game on Mind Skills Arcade, grouped by what it actually trains
This is the full catalogue: more than 140 free games, every one of them instant, browser-based and free of accounts, downloads and paywalls. They are grouped by the ability each one loads rather than by theme, because that is the only grouping that helps you pick.
Memory covers working memory, recall and recognition — Digit Span, Number Memory, Matching Pairs, Word Recall and Dual N-Back all live here. Logic covers deduction and planning: Sudoku, Logic Grid, Codebreaker, Lights Out, Knight's Tour.
Maths is timed arithmetic and number sense — Arithmetic 60s, Times Tables Sprint, Countdown Math. Focus and attention covers selection and inhibition, headed by the Stroop Test and Go/No-Go.
Reaction measures response speed in milliseconds. Spatial covers mental rotation, reflection and route memory. Word and language covers anagrams, vocabulary and recall. Typing measures WPM and accuracy.
Trivia, tracking, speed, timing and multitasking round out the set — tracking for shell games and object following, timing for rhythm and interval judgement, multitasking for the divided-attention drills.
Take the Reaction Time Test and the Number Memory Test first. Both take under ninety seconds and both give you a single number that moves visibly with practice, which makes them the easiest habits to keep.
Then pick one category that matches something you actually want to improve, and play one game from it daily for a week. Sampling twenty games once teaches you nothing; one game for seven days shows you a real curve.
You will get better at the games you play. That much is reliable, quick and uncontroversial.
Whether that improvement spreads to unrelated abilities is a genuinely contested question, and the larger, better-controlled studies have mostly failed to find it. Every game page on this site says so rather than implying otherwise.
What is well supported is that staying mentally and socially active is associated with better cognitive ageing. Playing something you enjoy, regularly, is a reasonable response to that. Paying a subscription for it is not.
More than 140, across thirteen categories. New ones are added regularly and listed on the updates page.
Yes. No account, no email, no download, no premium tier and no locked content.
The Reaction Time Test or the Number Memory Test. Both are under ninety seconds and both give you a number you can track from day one.
They reliably improve your performance at the games themselves. Evidence that this transfers to general cognitive ability is weak, and we would rather tell you that than sell you a subscription.
