Nothing to read
Every idea is taught by the machine itself. Pick up, place, drop the marble, watch. If it doesn't work, move something and drop it again — that's the whole loop, and it's the whole of engineering.
iPhone & iPad · Ages 5+
Build funny paper machines.
Drop the marble. Watch everything go klank. Klanki is a workshop that does exactly what your child tells it to — and nothing they didn't.

NOT ONE WORD IN THE WHOLE GAME
A five-year-old can start it alone.
There is no text in the child's half of Klanki. No tutorial to read, no menu to parse, no button that says Continue. A child picks up a plank because it looks like a plank, puts it where the marble should go, and finds out whether they were right.
Nothing to rush
No timers, no lives, no streaks, no score. A level waits as long as it takes. The reward for solving one is watching your machine actually run — we never found a sticker that beats that.
Nothing to tap by accident
Touch targets are 72 points, not the usual 44. One finger, one part at a time. No double-taps, no long-presses, no swipes to learn.
THE WORKSHOP
Twelve parts. Thirty-six levels. One sandbox with no rules at all.
Six chapters introduce one idea at a time — first a ramp, then a bounce, then things that spin, swing, topple and play a note. Then the sandbox hands over every part at once, adds a spiral, a lift and a switch, and gets out of the way.
Plank
The ramp. Everything starts here.
Springboard
Bounces the marble up and over.
Block
A wall, a step, or a thing to knock down.
Gear
Spins and flings whatever touches it.
Fan
Blows the marble sideways through the air.
Pendulum
Swings, waits, and hits at just the right moment.
Domino
Falls into the next one. And the next one.
Tube
Swallows the marble and spits it out elsewhere.
Xylophone
Every bar plays a note. Line them up and the marble plays a tune.
Spiral
The marble circles down behind the paper and rolls out calm.
Lift
The only way up: a bucket belt carries the marble to the top.
Switch
Sends one marble left and the next one right.
The sandbox
Level zero has no goal and never ends, and whatever is on the table is still there next time. Seventeen blueprints suggest machines to copy; build one and it earns a star, rebuild it from memory with no guides and it earns a second. Or ignore all of them and make something that has never worked in your life. That's allowed too.
The big table
One button unfolds the sandbox to three screens wide, and the camera follows the marble all the way along. Two blueprints are made for it: Old MacDonald, the whole song played by a marble on 26 paper xylophone bars, and Everything, which puts all twelve parts into one machine. The big table comes with the full version.
Two marbles, two roads. The switch sends the first one flying — springboard, crane, spiral — and the second along the ground, over a domino bridge. They meet at the lift, and then a geyser of two fans throws each one up to the ceiling.
PRIVACY IS THE ARCHITECTURE, NOT A FEATURE
There is nothing to collect.
App Store privacy label: Data Not Collected
The app never phones home
There is no Klanki server to talk to, no account to make, no email to give us. The only network traffic the app can cause belongs to Apple — the App Store if you buy the unlock, and your own iCloud if progress syncs. Neither one carries anything back to us. Play the whole game in airplane mode and nothing changes.
No analytics, no ads, no SDKs
Klanki has zero third-party code in it — no analytics, no advertising identifiers, no crash reporters. The App Store label reads "Data Not Collected" because there is genuinely nothing to collect.
Progress rides your own iCloud
Which levels are solved syncs between your family's devices through your personal iCloud, with no login and no copy on our side. Switch iCloud off and the game keeps every star locally.
The grown-up door stays shut
Buying, links and settings live behind a three-second press-and-hold that a child won't do by accident. Nothing in the child's half can spend money or open the web.
PRICE
Free to try. One payment for the rest.
Free
Chapter one — six levels — and the sandbox with the two starter parts, forever. Enough to know whether your child likes it before you pay anything.
One payment
The full workshop
All thirty-six levels, all twelve parts — ten more join the two starter ones — every blueprint, and the big table three screens wide. One purchase, no subscription, shared with your Family Sharing group.
- Family Sharing included
- Never a subscription
QUESTIONS
For the grown-ups
What age is it actually for?
Five and up is the honest answer, and plenty of four-year-olds manage it. Because nothing has to be read, the limit is patience rather than vocabulary. The later chapters will keep an eight-year-old busy.
Does it work offline?
Always. Klanki has no online mode to lose. The only moments it touches the network are the purchase itself and an iCloud sync of your stars — both run by Apple, not by us. Everything else works on a plane, in a car, and in a cottage with no signal.
Can my child spend money by accident?
No. The only buy button lives behind a grown-ups door: a three-second press-and-hold explained in written words — which is exactly the point, because the child the game is made for can't read them yet. If you use Ask to Buy, the request goes to the family organizer as usual.
I bought it. Why is it locked on the other iPad?
Open the grown-up door and tap Restore Purchases. If the other device uses the same Apple Account, that's all it takes. If it's a family member's own account, the unlock travels through Family Sharing — one purchase covers the whole family group, just make sure purchase sharing is turned on in your family settings.
Is progress saved if we get a new device?
Yes, provided iCloud is on — stars sync through your own iCloud with no account to make. Without iCloud, progress stays on the device it was earned on.
Are there ads or videos to watch?
No, and there never will be. Klanki is in the App Store's Kids Category, which forbids third-party ads and analytics — and we'd have skipped them anyway.
Give a child a plank and a marble.
Then get out of the way and watch what they build.
