## What is form9?

form9 is sudoku, played with shapes. The same 9×9 logic you know — but every cell holds one of nine quiet silhouettes instead of a digit.

Nothing to read, nothing to count — just pattern and logic. That makes it a natural fit for people with dyscalculia, kids still learning their numbers, language learners, and anyone who simply thinks in shapes.

• A fresh daily puzzle, with a streak to keep
• Five difficulties — Easy, Medium, Hard, Expert, and Master
• Notes, undo, hints, and gentle error highlighting
• Colorblind-friendly by design — shapes carry the meaning, not colors. Nothing to toggle.
• Full VoiceOver support — every shape has a clear spoken name
• Optional color-hint mode for a redundant cue
• Reduce Motion respected
• No ads. No tracking. Ever.

form9 Pro (one-time purchase) unlocks:
• Expert & Master difficulty
• Statistics — best times, completions, hint-free streaks
• The daily archive — replay any past puzzle

Made by a solo developer who believes a good logic puzzle deserves a calm, quiet home.

A small update - and a bigger celebration.

  • [FEATURE] Celebrations now fill the screen - confetti and balloons carry on over the board while you line up the next puzzle.
  • [FEATURE] The score card now rises over the board - swipe it down or tap the board to leave.
  • [FEATURE] form9 follows your device language. Change it in your phone's language settings and the app follows.

### 1.1.1 — 2026-08-20

A small update — and a new alphabet.

  • [FEATURE] ABC shapes — a third set of nine, drawn as the letters A to I. Free for everyone, switch whenever you like in Settings.
  • [FEATURE] Balloons for a special win — a new personal best or a flawless daily now sets nine balloons loose. Pop them all if you can.
  • [FEATURE] form9 now speaks French, alongside English, German and Polish.
  • [FEATURE] VoiceOver now reads the shape set you actually play with, so letters are spoken as letters.

### 1.1.0 — 2026-08-19

A bigger update this time — and still entirely optional.

  • [FEATURE] Game Center — 40 achievements and a leaderboard for every difficulty. Signing in is optional; without it nothing changes and the game stays fully offline.

  • [FEATURE] A new home screen — it opens on today: the Daily Challenge up top with a peek at the board, your streak for the week, and a quick-play row for the level you played last.
  • [FEATURE] A card that rotates through what's worth knowing — the new shapes, how you're doing, and settings you may not have found yet.

### 1.0.4 — 2026-07-13

A little update — still calm as ever.

  • [FEATURE] Share your result — turn any solve into an image card (the board, your points, time and streak, plus a Flawless badge for a run with no mistakes or hints) and send it to chat or social.
  • [FEATURE] Update reminder — the daily archive now lets you know when a newer form9 is ready to install, alongside the nudge to leave a review.
