iOS App — Free
Trilumin
Three puzzles. Zero noise. Pure clarity.
A minimalist logic puzzle app for people who think deeply — and need a moment to stop thinking at all.
Designed for focus
Three puzzles, one calm
Sudoku
The classic, stripped to its essence. No colors, no themes. Just you and the numbers.
Futoshiki
Numbers meet inequalities. A lesser-known puzzle that sharpens logical reasoning with every cell.
Gokigen
Fill cells with diagonal lines following simple rules. Deceptively simple. Deeply satisfying.
Built different
No ads by default
Trilumin is completely free with no in-app purchases. Ads only appear when you choose — watch one for a second chance after losing. Your choice, always.
ADHD-friendly design
Clean interfaces. No flashing elements. No timers unless you want them. Built for minds that need calm, not chaos.
Offline-first
No internet required. No accounts. No syncing. Your puzzles, your device, your pace.
Designed with care
Every pixel considered. Every interaction intentional. A puzzle app that respects your intelligence and your time.
Five minutes of focused puzzling can reset your entire afternoon.
