One daily brain training game every day.
Sent to your inbox every day.
Track your scores and progress over time.
Each morning we email you a link to that day’s game. No app to download and nothing to install — you tap the link and play.
Every game is built to be done in a single sitting and then left alone. Tomorrow there’s a different one.
Miss a day and there’s no backlog waiting. Every game stays on this page — play today’s, or pick whichever one you fancy.
Today’s is already selected for you. You can play any of the others whenever you like — they don’t expire, and they’re not in any particular order.
Putting a name to a face
You meet someone, they tell you their name, and three seconds later it’s gone. It’s the single most common complaint people have about their own memory, and it’s a specific skill — tying a piece of information to a face. Today you learn a few, then get asked again after a break.
Holding a list in your head
You read the list at the kitchen table and do the shop twenty minutes later. What usually survives that gap is the gist rather than the specifics — you remember you needed something from the dairy aisle, but not whether it was milk or cream. Today’s shelf is stocked to catch exactly that.
Remembering places, not things
Knowing what you’re looking for and knowing where you left it are two different jobs. Today is the second one: a few everyday things get left around a house, and you have to say which room each one ended up in. It’s the keys-and-glasses problem, in miniature.
Finding the word you already know
This one isn’t about holding on to something new. You already know these words — the job is reaching them. That reaching gets slower before anything else does, and it’s the most frustrating kind of slip because you can feel the word sitting there. There’s no clock on today’s game for exactly that reason.
Keeping something in the air
Somebody reads out a number and you have to keep hold of it just long enough to use it. Today asks you to give a few back — first as they came, then in reverse, which is harder because you’re holding the number and turning it round at the same time. The shortest game of the week.
What stays with you from reading
You read a chapter last night and this morning you couldn’t say what was in it. Today’s story is short and ordinary, and the questions afterwards are mostly about small things nobody told you to remember — which is how reading actually works. Don’t try to memorise it. Just read it.
A bit of everything
One short go at each of the week’s six games in a single sitting, and one number at the end. It won’t tell you anything the individual days don’t, but it does show you at a glance which kind of remembering came easiest this week and which gave you the most trouble.
The game opens on our practice site in a new tab. Nothing is saved.
Koya Brain Training is the free companion to a 90-day supply of Koya. One capsule of bacopa monnieri a day, with food — that’s the whole product. No caffeine, no fillers, no stack of twenty other things.
Every game ends with a number out of 100. It’s there to give the game a shape and a finish line — not to grade you. It swings around a good deal depending on how you slept, how much was going on around you, and whether you’ve played that particular game before.
Once sign-in is ready, the games you’ve played will show up here as one simple line over time. This is roughly what that tends to look like:
This example drifts upward — a good deal of that is just getting the hang of each game. Real scores jump around too: sleep and distraction move them more than anything else, and a single low day isn’t worth reading into. What counts is turning up, not the number.

Sign-in and saved scores — coming soonNo. It’s there if you want it. Some people do one a day with their morning coffee; others do a few a week. There’s no streak to keep up and nothing nags you.
Nothing happens. The game doesn’t disappear and there’s nothing to catch up on. Open the page and play whichever one you like.
Not yet. Right now your score vanishes the moment you close the page — there’s no history and nothing to compare. Saved scores and a sign-in are coming; when they do, they’ll be yours alone and never measured against anyone else’s.
No. These are exercises, for practice and for the small satisfaction of doing them. They are not a screening tool and the score is not a measure of your health.
One ingredient: bacopa monnieri. One capsule a day with food, thirty days to a bottle.
