## What is Ninefall?

Every tile holds a number. Play one of yours onto it: the values add, the tile flips, and every lower-numbered neighbor topples after it, domino-chaining across the board. The catch: past 9, numbers roll over. 6 + 6 = 2.

The goal: clear it all with a handful of numbers. That one rule hides the depth. Greed has a price, nines are fortresses, zeros are scalpels. And one perfect placement can flip the whole board in a single, glorious GRAND CASCADE.

A JOURNEY OF SIX WORLDS
72 hand-calibrated levels teach the game by play, never by text. Stones block, seals lock, ice cracks, bombs level everything beside them, traps must never flip, and wormholes carry your cascade across the board. Collect a world's gems and its secret level appears.

EVERY LEVEL CERTIFIED FAIR
Each puzzle ships machine-verified: always solvable, par always exact, never cheap. Unlimited undo and a solver-powered hint are built in. Thinky, never punishing.

THE DAILY FLIP
One board, the whole world, every day. Keep your streak (one automatic repair a month, because life happens), and share your result without spoilers.

FLOURISHES, NOT STARS
Every level carries one optional master-goal: clear it in a single placement, never roll over, end on a 9. No grinding, no ratings, just elegance.

MADE LIKE A TOY
Chunky ceramic tiles that flip with real weight, synthesized marimba cascades that climb as your chain grows, haptics choreographed to every topple, Day and Night themes, a home-screen widget for your streak.

PRIVATE BY DESIGN
No ads, no tracking, no account. The whole game in one download, playable offline.
