description Mochikoro Overview

Mochikoro is a Japanese logic puzzle published by Nikoli, sharing similarities with the better-known Nurikabe puzzle. In Mochikoro, solvers must create rectangular white islands of the size indicated by numbered cells, while ensuring that all shaded cells form a single connected region without any 2x2 blocks of shaded cells. Unlike Nurikabe, where islands must have exactly one number, Mochikoro islands can contain multiple numbers as long as the total size matches the sum of the numbers within.

help Mochikoro FAQ

What is Mochikoro?

Mochikoro is a Japanese logic puzzle published by Nikoli. It resembles Nurikabe because solvers shade cells and manage connected regions, but its white areas must be rectangular islands.

What do the numbers mean in Mochikoro?

A numbered cell gives the required size of the rectangular white island containing it. The solver must arrange the white cells so each numbered island has the stated area.

How are shaded cells connected in Mochikoro?

All shaded cells must form one connected region according to the puzzle's standard adjacency rule. The white islands must remain separate and rectangular while satisfying their numbers.

How is Mochikoro different from Nurikabe?

Both puzzles involve numbered white regions and a connected shaded area, but Mochikoro specifically requires rectangular white islands. That rectangle rule changes the deductions compared with ordinary Nurikabe.
