Klanki — Marble Machines

Build a paper machine, drop the marble, watch it go klank. Wordless contraption puzzles a five-year-old solves alone — no reading, no timers, no way to fail.

Build funny paper machines. Drop the marble. Watch everything go klank!

Klanki is the building game a five-year-old plays without reading a word — bought once, no subscription. Pick up a plank because it looks like a plank, put it where the marble should go, and find out whether you were right. That's the whole loop, and it's the whole of engineering.

WHAT'S INSIDE • 30 handcrafted levels across 5 chapters — each chapter introduces a new part • An endless sandbox with 7 blueprint machines to copy, master and remix • 8 paper parts: plank, springboard, block, gear, fan, pendulum, domino and tube • A hand-drawn paper world with playful sounds and gentle haptics

MADE FOR NON-READERS There is not one word in the child's half of the game. No tutorial to read, no menu to parse, no button that says Continue. And no timers, no lives, no score — a level waits as long as it takes. The reward is watching your own machine actually work.

PARENTS CAN RELAX • No ads and no third-party anything — the App Store privacy label says Data Not Collected, because there is nothing to collect • Works fully offline: planes, road trips, cottages with no signal • Buying, links and settings live behind a grown-ups-only gate • One purchase opens everything, forever — shared with your family through Family Sharing • Progress syncs through your own iCloud, with no account to make

Chapter 1 and the starter sandbox are free. One purchase opens all 30 levels, all 8 parts and every blueprint. And every day one more part visits the free sandbox as a guest — a gear today, a fan tomorrow.
