About this app
Islefall Sea Islands is a complete, offline island region-fill puzzle for anyone who loves a clean logic challenge. Every archipelago is generated fresh on your device — no two puzzles are ever quite the same, and no internet connection is ever needed.
THE RULES ARE SIMPLE, THE SOLVES ARE DEEP
Each numbered cell is the seed of an island. Grow it, by tapping neighboring cells, until it holds exactly that many cells — no more, no fewer. Two different islands can never touch, not even at a corner. Everything that isn't island becomes open sea, and that sea must always stay a single connected body of water with no hidden 2x2 pocket sealed off from the rest. Get every rule right at once and the map is charted.
LIVE FEEDBACK, NO GUESSWORK
An island that's grown too big, two islands touching, or a sealed-off patch of sea all turn a warm coral warning the instant they happen, so you always know exactly what to fix — no wasted moves.
THREE SIZES, ONE FRESH PUZZLE EVERY DAY
Pick Easy (5x5), Medium (7x7), or Hard (10x10) from the New tab whenever you want a puzzle generated on the spot. Or open the Daily tab for a single shared archipelago that's the same for every player that day, and build a streak by coming back.
LEARN AT YOUR OWN PACE
The Learn tab walks through every rule in plain language and includes a tiny hands-on puzzle so you can try the mechanic before diving into a full grid.
TRACK YOUR PROGRESS
The Awards tab unlocks badges as you solve more puzzles, clear every grid size, post a fast time, and keep your Daily streak alive.
DESIGNED TO STAY OUT OF YOUR WAY
- Fully offline. No internet connection is used or required.
- No ads. No accounts. No analytics. No tracking of any kind.
- No sound — every cue is visual, backed by a light haptic tap.
- A calm ocean-and-sand theme built for relaxed, focused solving sessions.
Whether you have two minutes or twenty, Islefall Sea Islands turns a handful of numbers into a satisfying logic puzzle every time — fresh, fair, and entirely yours to solve.
