Prisma is Sudoku the way it should feel: calm, clear and beautiful. Every puzzle you solve charges a glowing light artifact. Piece by piece it grows into your very own constellation - a visible record of every solved puzzle. No point hoarding, no energy limits, no pop-ups. Just you, the puzzle and a little more light after every win. NO ADS, NO BARRIERS No ads. No subscriptions. No accounts. No hidden barriers. There is a voluntary tip jar - leave a light if you like. But tips never unlock content or features: everything in the game is open to everyone from the start. THREE WAYS TO PLAY • Classic - the Sudoku you know and love • Diagonal (X-Sudoku) - both diagonals also carry the numbers 1 to 9 • Killer - cages with sums instead of starting numbers, for those who want more of a challenge Each mode in five difficulty levels from Easy to Diabolical. DESIGN THAT BRINGS CALM A board like glass: soft "liquid glass" surfaces, warm light, subtle haptics and gentle tones. Light and dark mode included. Built for iOS - with real materials, smooth animations and motion parallax in the constellation. THOUGHTFUL SUDOKU • Daily puzzle with streak counter - a new, fair puzzle every day • Notes, hints, unlimited undo • Highlighting of matching numbers and automatic cleanup of notes • Unique solutions - every puzzle is cleanly solvable • "Continue playing": your current game is always right where you left it COLLECT INSTEAD OF GRIND 36 artifacts wait to be charged - prisms, orbs and light cores in warm and cool tones. All purely cosmetic and reachable by everyone - nothing needs to be unlocked. In the gallery you see your progress; in the stats your best times, daily streaks and 12 achievements. OFFLINE & PRIVATE Prisma runs completely offline. There are no user accounts and no tracking. Your saves stay on your device. Enjoy solving. May your constellations shine bright. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Funke | $0.99 | one-time | | Glimmen | $1.99 | one-time | | Strahlen | $2.99 | one-time | | Leuchtfeuer | $3.99 | one-time | ## Version history (last 5 releases) ### 2.1.1 — 2026-07-10 Bug fix: In rare cases the app could crash when placing the final number of a puzzle.
