A clean, satisfying logic game: every outlined region must contain exactly two shaded cells, and every shaded cell must belong to a domino (a 1×2 or 2×1 block). Dominoes can touch diagonally, but never side-by-side. Choose a grid size and start solving — infinite levels included.
Tip: Tap to shade • Double‑tap to dot • Right‑click to dot
Norinori is a clean deduction game built around one idea: shaded cells must form tidy dominoes. Each board is split into outlined regions (the thick borders). Your job is to decide which cells are shaded and which are empty so every rule is satisfied at once. No guessing is needed — every move can be justified by logic.
Every outlined region must contain exactly two shaded cells. Treat each region like a container with a strict capacity: once you’ve placed two shaded cells, everything else in that region becomes unshaded (mark them with dots to stay organized). Small regions are the fastest progress — if a region has only two cells, both must be shaded. If a region has three cells, exactly one must be unshaded, which often forces the shape of a domino nearby.
Shaded cells must come in pairs as 1×2 or 2×1 dominoes. That means each shaded cell must have exactly one orthogonal shaded neighbor. If a shaded cell is isolated, it can’t be part of a domino. If it touches two shaded neighbors, you’ve made a “T” or a cluster — also invalid. This rule is powerful: once a cell must be shaded, it immediately demands its partner.
Different dominoes may not touch orthogonally. Diagonal contact is allowed, but if two dominoes touch edge-to-edge, some cell would have more than one shaded neighbor — breaking the domino structure. In practice, when you place a domino you can often dot the four side-adjacent cells around it, because no other domino can shade those squares.
A reliable loop is: (1) scan for tiny regions, (2) place forced dominoes, (3) dot “forbidden” cells next to completed dominoes, (4) re-check regions that are now nearly full. If you ever feel stuck, look for a region that can only fit two shaded cells in one remaining pattern — then propagate the domino and no-touch consequences outward.
When you’re ready, press Check. If something is wrong, conflicting cells are highlighted so you can undo and continue. Every time you hit New Game, Norinori generates a fresh board, so you can keep playing without running out of levels.
