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 TalkBack support — every shape has a clear spoken name
• Optional color-hint mode for a redundant cue
• Reduce Motion respected
• Plays offline — no internet, no account
• 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.
