Boilerplate

Ninefall is a chain-reaction number puzzle for iPhone and iPad. Every tile holds a number: play one from your hand and the values add, the tile flips, and every lower-numbered neighbour topples after it. Past nine, numbers roll over, so 6 + 6 = 2. Across eight worlds and 96 hand-calibrated levels, every board ships machine-verified as solvable in its par. It costs $4.99 once, has no ads, no in-app purchases and no tracking, and the whole game fits in 3.3 MB. Made by one person, Thomas Sobstyl.

Angles that might interest you

  • Every level carries a proof. A solver verifies each board before it ships: solvable, par exact, master goal reachable. The witness is stored with the level and re-checked on every build.
  • 3.3 megabytes. No game engine, no cross-platform framework, no third-party code. Written natively, which is why it is smaller than most screenshots of it.
  • A daily puzzle with no server. The Daily Flip is generated on the device from the date alone, so the whole world gets the same board with no account, no backend and no analytics.
  • Paid, once, on purpose. No lives, no energy, no hint packs. The two worlds added after launch were free.
  • One person. Design, code, art, sound, nine localisations and the level solver.

Logo usage

  • The cascade mark is always full colour. Please do not recolour it.
  • Keep clear space of at least the height of the wordmark's N on all sides.
  • Minimum sizes: wordmark 90 px wide, cascade mark 96 px, app icon 40 px.
  • The wordmark is two-tone: NINE in ink, FALL in coral.
