Clink & Think
A gentle marble puzzle for little thinkers.
Drop glossy marbles into glass tubes — count, match, sort, pattern and mix. Made for ages 4–6.
iPhone, iPad & iPhone Duo · iOS 17+ · Free to play, one-time Full Unlock
Built for little hands and curious minds
Clink & Think turns early-learning into cosy, tactile play — no reading required, nothing scary, nothing to rush.
Counting & colours
A free Learn mode teaches numbers, colours, and left/middle/right with a friendly spoken voice.
A voice that guides
A friendly voice talks children through Learn, Pattern and Memory, in English, French, Spanish, Portuguese, Italian or German — follows your device or pick one.
An Adventure to grow into
A friendly level map of worlds — clear a world to earn its marble theme (fruit, animals, dinosaurs, space…).
Make it theirs
Earn stickers, decorate a Playroom, and collect glossy marble themes as they play.
Gentle play-time limits
Set a daily limit in Settings. When time is up, a calm wind-down says goodbye — never mid-puzzle — and a weekly summary shows grown-ups what was practised.
iCloud sync
Progress follows the child across their own iPhone and iPad automatically.
Private by design
No accounts, no ads, no analytics, no data collection. It simply works offline.
Made for iPhone Duo
Half-fold an iPhone Duo and Clink & Think splits in two, like a little play table: the goal stands up where your child can see it, and the tubes, tray and buttons lie flat under their hands — so every marble is dragged on one side of the fold, never across it. New in version 1.4.

Every screen splits
All seven game modes, Home, the Adventure map, the Sticker Book and Playroom, and the grown-up screens — the parental gate's keypad lies flat, its question stands up.
Touch stays flat
Pop-ups like “You did it!” appear on the flat half, right under little fingers, never across the hinge.
Open or closed
Fully open, the game uses the whole big screen. Closed, the menu fills the outer display, clear of the camera.
Nine ways to play
Gentle modes that grow with your child — from a no-rules sandbox to colour-mixing science. Tap any mode for a step-by-step how to play.
