Island Planet
Eric Caginicolau
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.
