description Sukoro Overview
Sukoro is a Nikoli logic puzzle in which the player fills selected cells with numbers from 1 to 4. Each numbered cell indicates how many filled cells touch it vertically or horizontally, and equal numbers may not be adjacent in those directions. All filled cells must form one orthogonally connected group, so the puzzle combines local counting clues with a global connectivity requirement. It is intended for solvers who enjoy grid-based deduction and number-placement puzzles.
help Sukoro FAQ
How do you play Sukoro?
In Sukoro, you fill selected cells with numbers from 1 to 4. Each numbered cell tells you how many filled cells touch it vertically or horizontally.
Can equal numbers touch in Sukoro?
No. Equal numbers may not be adjacent vertically or horizontally, so a legal solution must satisfy both the clue counts and the separation rule.
Do all filled cells need to connect in Sukoro?
Yes. All filled cells must form one orthogonally connected group, meaning every filled cell must be reachable through vertical or horizontal links.
How is Sukoro different from Sudoku?
Sukoro is a Nikoli logic puzzle based on adjacency counts, connected regions, and values from 1 to 4. Sudoku instead uses repeated number-placement constraints across rows, columns, and boxes.
