What counts as a brain game here

Every game on this page asks your mind for one specific job and gives you a score for it. Memory games ask you to hold something for a few seconds — digits, positions, pairs or an order. Focus and reaction games ask for a short, sharp burst of attention. Logic and puzzle games ask you to slow down, deduce and plan. Number and word games ask you to pull facts and calculations out of memory quickly.

All of them are free, run in the browser on a phone or computer, and need no account. Most rounds last one to five minutes, which is why they work well as short mental games between other things.

How to pick a game

Choose by what you want from the next few minutes rather than by which game sounds hardest:

Short and often beats long and rare

Scores in these games move a lot from one round to the next because attention, sleep and even the device you use change them. A fair way to play is a few minutes at a time, mixing two or three different areas, and comparing your score with your own earlier results instead of a single lucky round. That is what the quick brain routine above does: it draws three short games from three different areas so you are not repeating the same skill.

Several games also have a leaderboard. It is a fun target, but the people near the top have usually played many rounds; your first score is a starting point, not a verdict.

For teens, adults and classrooms

The same games work across ages because each one starts easy and gets harder only as you succeed. Teenagers tend to enjoy the competitive ones — the Chimp Test, Reaction Time and Connect Four — while adults often prefer a calm sudoku or nonogram as a break. In class, a two-minute memory or reaction game makes a quick warm-up, and the quizzes double as review.

Psychologists group several of these skills under executive functions: working memory (holding and updating information — the memory games), inhibitory control (waiting for the right moment — the reaction test) and planning (thinking moves ahead — the puzzles and board games). The games give each of those a concrete, playable form.

An honest note on what brain games do

Practising a game reliably makes you better at that game, and the scores here are a fair way to see your memory, attention or reasoning on a given day. What research has not shown is that a few minutes of brain games raise intelligence or protect against illness — improvements mostly stay close to the task you practised. So treat these as what they are: short, free games that give your mind a specific workout, a bit of fun and an honest score.

Frequently asked questions

Are these brain games free? Do I need to sign up?
All 24 games are free and need no account or download. They run in the browser on phones, tablets and computers. Some games let you add your score to a leaderboard with a nickname, but that is optional.
Do brain games make you smarter?
Practice makes you better at the games themselves, and they are a good way to check your memory, focus or reasoning on a given day. Research has not shown that short brain games raise general intelligence; gains mostly stay close to the skill you practise. Play them because they are fun and give you a clear score.
What are good quick brain games for a short break?
Reaction Time Test, Click Speed and Aim Trainer take under two minutes. Number Memory, Sequence Memory and the Chimp Test take about three. If you have about ten minutes, press “Draw a routine” and play the three games it picks from different areas; it shows the total time.
Which brain games are good for teenagers?
Teenagers usually enjoy the games with a score to beat or an opponent: the Chimp Test, Reaction Time Test, Aim Trainer, Connect Four and Gomoku. For school-style practice, the Mental Math Drill, Multiplication Quiz and Capital Cities Quiz work well.
Which games train executive functions?
Working memory is used most in Number Memory, Sequence Memory, Visual Memory and the Chimp Test. Inhibitory control — waiting instead of reacting too early — is central to the Reaction Time Test. Planning ahead is what Sudoku, the 15 Puzzle, Othello, Connect Four and Gomoku reward.
Do the games work on a phone?
Yes. Every game supports touch, and boards resize to fit the screen. The Typing Speed Test and Click Speed test feel different on a touchscreen, so compare phone scores with phone scores.
