Tentang game ini

Insula is a Nurikabe puzzle — also known as Islands in the Stream — for players who like unhurried, honest logic.

Every number marks an island of exactly that many cells. Every island holds exactly one number, and islands never touch horizontally or vertically. Everything else is sea: one connected ocean that nowhere forms a solid 2x2 block of water.

Never a guess

Every puzzle has exactly one solution, and every step of it can be reasoned out. Each board is verified by a solver that only uses techniques a person can follow and explain — so a puzzle that would need trial and error never ships. The hint button uses that same solver, which means a hint is always a move you could have found yourself, and it tells you which idea it used.

Learn it by playing it

Nurikabe does not explain itself the way most grid puzzles do: two of its rules are about the board as a whole. The walkthrough hands you real positions and asks for the one square that follows, then shows you why. No board in it was made up — each is a genuine puzzle stopped at the moment the idea it teaches becomes the forced next move.
