MIKIRI is a free brain game site with 19 mini games that put your head and eyes to work: remember a flashed number, add up a stream of numbers, follow one dot among many, read where a movement is going. Each game uses a different kind of thinking, so your strong and weak spots show clearly. Runs start at about a minute, and your days are kept on a calendar.

An honest note about brain training

Getting better at a game is not the same as changing everyday memory or judgement. Research has not reached a clear conclusion on the long-term effects of brain training (see what brain training research shows). MIKIRI is for enjoying using your head and keeping a record of the day.

FAQ

Are they free?

Yes. All 20 games are free, with no account and no app to install.

How much should I play each day?

There is no rule. Many games take about a minute, so one or two runs in a spare moment is an easy start.

Which brain game should I start with?

If you like numbers, try ANZAN (flash mental math); for memory, BLINK HUNT; for attention, SENKO. If unsure, start with FLASH.

Can anyone play, at any age?

Yes. Every game starts easy and gets harder step by step. Take a break if your eyes feel tired.

Is this a medical test?

No. MIKIRI is a set of games for fun and self-tracking, not a medical test or diagnosis.
