Free Mind Games Online — Built for Adults, Not Ad Farms
Every mind game on this site runs directly in your browser: no download, no account, no app store. Play chess, draughts or xiangqi against the computer, solve go life-and-death problems, sharpen your bridge bidding, or take on sudoku and memory matrix. Most free brain-game portals optimize for ad impressions; this one is built around the classic mind sports — games deep enough that federations run world championships in them.
A Daily Puzzle Worth Keeping a Streak For
Once a day, at midnight UTC, a new Stones puzzle goes live: place one stone in every row, column and region without any two touching. The rules take ten seconds to learn; the harder grids will hold you for a quarter of an hour. Your streak and times stay on your device — solve it, share your result, come back tomorrow.
Test Your Mind, Then Train It Properly
The Mind Lab measures the fundamentals — reaction time, sequence memory, number memory and the notorious dual n-back — with percentile comparisons against published population data. And when you’re done measuring, our evidence-based brain training guide explains what the research actually supports, from the ACTIVE trial to the FTC’s Lumosity case. Short version: skip the subscription, learn a real mind sport instead.
Are all the games on this site free?
Yes. Every game and test runs free in your browser with no account, no download and no in-app purchases. Progress like streaks and best scores is stored locally on your device.
Which mind games can I play against the computer?
Chess, draughts (English 8×8 and international 10×10) and xiangqi all have playable boards with adjustable difficulty. Go is covered by a life-and-death problem trainer, and bridge by a bidding-judgment quiz.
Do mind games make you smarter?
You get better at the games you practice — that part is well documented. Claims of broad IQ gains are not supported by the research; our brain training guide covers the evidence honestly.
What is the daily puzzle?
Stones is an original placement puzzle in the constraint-grid family: one stone per row, column and region, no two adjacent. A new puzzle appears every day at midnight UTC, with streaks and shareable results.
Do the games work on a phone?
Yes — every board and test supports touch input and scales down to small screens. Once a page has loaded, the game itself runs entirely on your device.
What were the World Mind Games?
An annual international competition held in Beijing from 2011 to 2014, bringing elite chess, go, draughts, xiangqi and bridge players together. The full results and stories are preserved in our history section.
