The gamesEvery game is
Every game is
its own little world.
No flashcards, no quizzes in disguise. Balance a listing barge, crack a shopkeeper’s window, find the cookie Milo ordered. The thinking is the game, and each one has its own level to climb.
The Barge Biscuit
She’s listing to port. Shift crates across the deck until both sides weigh exactly the same.
Bo’s Curio Shop
Bo dressed the window in secret. Each try tells you how close you are. Crack it in as few as you can.
The Night Block
Windows light up, the block goes dark, and you tap them back. Later: in order, backwards, or only the ones with a cat.
Wren’s Library
Every shelf follows a hidden rule. Work it out, then fetch the missing book.
The Kitchen Pass
Tickets come down the rail one at a time. Keep service straight while new orders keep coming.
The Rooftop Party
Who brought what? Cross off what can’t be true from a few clues, one sure deduction at a time.
The Market Stall
Bag something new every time. The vendor reshuffles the stall after each pick, and the bag stays shut.
Night at the Gallery
Study the exhibits. Lights off. Lights on: something was swapped in the dark. Which one?
Fishing in the Fog
Cast for clues, then radio in which cove the current carried you to, once you’re sure enough.
The Rail Yard
Shunt cars between sidings until the yard matches the departure board, in as few moves as you can.
The Paint Counter
Work out the scoops for the recipe, pour, then stir. The colour only blends once you commit.
The Laundromat
One washer, one dryer, a pile of baskets. Find the order that finishes the day soonest.
The Party Shop
Every guest needs a cup. Fill the basket for the least money, then check the receipt.

This is Visual Search, one of 34 games in thinkin. Find the twin among the look-alikes. Same cutter, same icing, bitten or not.
Pick the wrong one and Milo tells you exactly what you missed. Every game works like that: you learn from the miss, not just the score.

How it worksA few minutes a day.
A few minutes a day.
Always just hard enough.
Open the app, play today’s games, get on with your day. thinkin keeps track of what you’re good at and what’s next.
01
A fresh workout, every day
Each day thinkin picks three games from different skills, starting with the ones you said you care about. Quick warm-up first, puzzle last. Done in minutes.
02
Every miss teaches you something
Get one wrong and you’ll see why: the hidden rule, the working, or the one detail you missed. No shrug, no buzzer.
03
It grows with you
Every game has its own level. Every round you finish adds to its bar, good rounds add more, and a level is never taken away. Meanwhile the games get harder as you improve and ease off when it gets too much.
The honest part
We won’t promise you a higher IQ.
Nobody honestly can. What we can promise: games built on tasks researchers have used for decades to study attention, memory and reasoning, progress you can actually measure inside each game, and a daily habit that’s a pleasure to keep.
Measured, not guessed
Each game keeps your own bests, so you can see real progress, plus a level that climbs with every round you finish. No mystery “brain score”.
No ads. No account. No tracking.
Your progress lives on your iPhone, and nothing about you is sent anywhere.
Made to be enjoyed
Characters, little stories and real game feel, because a habit you like is a habit you keep.

These tasks are widely used to study how attention and memory work. Getting better at a game means you’re better at that game; we don’t claim it carries over to everything else.
Free.
All of it.
Every game, every day, nothing locked. Start now and it stays that way for you.

Will thinkin make me smarter?
We won’t claim that, and you should be wary of anyone who does. With practice you’ll get better at the games, and you can see it in your new bests, game by game, while each game’s level shows how much you’ve played. What we promise is a few minutes a day of genuinely good thinking that’s fun to come back to.
How long does it take each day?
The daily workout is three games, usually a few minutes in total. Make it five in Settings, or practice any game whenever you like.
I’m not a numbers person. Is it for me?
Yes. There are eight skills, from memory and focus to reading and spatial sense, and every game starts gently. Each one gets harder as you improve, and most ease off after a tough round, and every round you finish counts toward its level.
Is it really free?
Yes. All 34 games, the daily workout, levels and trends are free, with no ads and no account. If we ever add paid extras, everyone who’s playing now keeps everything, free.
