Fifteen years ago, this game lived on the iPhone 3GS. It's back. Same Nurikabe rules, new spherical world. No ads, no tracking, no fuss.
Island Planet reimagines Nurikabe by wrapping it around a spherical planet. You tap, you shape islands, you decipher clues. All in a cosy atmosphere, with no ads, no tracking, and no internet connection required.
— GAMEPLAY —
Nurikabe is a classic Japanese logic puzzle: each number tells you the exact size of an island you must build. Islands cannot touch. The ocean must stay connected, with no 2×2 ocean block anywhere.
On Island Planet, the grid is not a flat rectangle — it wraps around a whole planet. 6 faces, up to 1,536 cells, and every island wraps seamlessly across the cube edges. Spin the planet, zoom in, play one-handed in portrait mode.
— PROGRESSION —
• 4 difficulty tiers (4×4 face up to 8×8 face)
• Over 60 hand-curated puzzles
• Guided tutorial for newcomers
• 1 to 3 stars per puzzle, gated unlocks via Discoveries
• Expedition and Scout system for hints when you're stuck
— PHILOSOPHY —
No ads. No in-app purchases. No accounts. No data collected, ever. Your progress saves locally on your device. It's a game you play five minutes at a time, to sit down, think, breathe.
— HERITAGE —
Island Planet is the reinvention of my original game released on iPhone 3G/3GS 15 years ago, rebuilt from scratch in Unreal Engine 5. Same rules, fresh look.
Safe exploration on your planet.
