A grid of numbers hides every domino exactly once. Find where each piece belongs.
Tsugi is a dominosa puzzle: quiet, exact, and solvable by reasoning alone. Every board has one solution, and no part of it is guesswork.
NINE LEVELS, SEED TO OAK
Each level adds one number — and with it, pairs that did not exist before. The Seed, The Sprout, The Sapling, on to The Oak.
THREE WAYS TO PLAY
• Story — the nine levels in order
• Unlimited — any level, any time
• Daily Challenge — one new puzzle each day
HINTS WITHOUT LIMIT
A hint reveals one correct placement, as often as needed. Being stuck is never the end of a session.
MENDED IN GOLD
The name comes from kintsugi, the Japanese repair of broken pottery with gold. Solve a board and its seams seal in gold: the flaw becomes the ornament.
QUIET BY DESIGN
No timers. No score. No streak to defend. Only the next piece.
FAIR BY DESIGN
Pay once. No ads, no in-app purchases, no account, no tracking. Nothing is sent anywhere — progress stays on the device.
IN YOUR LANGUAGE
Tsugi speaks 44 languages. The whole app — board, levels, settings.
ON BOTH SCREENS
It fits the iPad, too: a bigger board, built for the bigger screen.
VoiceOver reads each cell by row, column and value, every control carries a label, and animations follow Reduce Motion.
