Meowdoku!! Level 37 Solution: How to Solve Without Mistakes

To solve Level 37 in Meowdoku!! without triggering mistakes, start by identifying the most constrained colored region on the board, place your guaranteed cat, and mark its entire row, column, and all eight surrounding squares with cross markers. You can then clear the rest of the puzzle through pure deduction by placing cats only when a row, column, or color zone is reduced to a single legal square.

Core Rules Governing Level 37

Level 37 requires you to place cats on the grid according to three strict conditions:

• Row and column limits: Exactly one cat must appear in every horizontal row and vertical column.
• Color territory limits: Exactly one cat must appear in each colored sector.
• Non-touching rule: No two cats may touch each other at any point, including diagonally adjacent tiles.

Placing a cat eliminates its entire horizontal row, its vertical column, and the surrounding three-by-three box centered on that tile. Because guessing can easily eliminate all legal placements in a later column or sector, use the cross marker to shade out invalid squares before tapping to confirm any cat placement.

Prioritizing Constrained Color Regions

Do not start by scanning rows or columns sequentially. Instead, examine the shape and square count of each colored sector to find forced placements or shared exclusions.

When a colored zone is restricted to two adjacent squares, any cell in an adjacent row or column that touches both candidate spots cannot legally contain a cat. Marking those shared neighbor cells with crosses reduces the board's open space before you even commit to the final cat position within that zone.

Chaining Diagonal Exclusions and Line Sweeps

The diagonal exclusion rule is the primary engine for creating chain reactions across the board:

1. Mark the eight-tile perimeter: The moment you place a cat, cross out all horizontally, vertically, and diagonally adjacent tiles.
2. Check adjacent color zones: Diagonal cross-outs frequently cut into neighboring color sectors. If a neighboring zone is left with only one unmarked square, place a cat there immediately.
3. Sweep full lines: Placing a cat completes that row and column. Immediately place crosses across every other empty square in that row and column.
4. Scan intersecting lines: Horizontal and vertical sweeps reveal solitary open squares in intersecting columns or rows. Treat each newly exposed single tile as a mandatory placement.

Resolving 50/50 Traps Without Guessing

If you reach a point where two color regions present paired two-cell choices, do not guess. Test candidate tiles by looking at the lines passing through them:

• Look down the column and across the row of a potential placement.
• If placing a cat on that tile eliminates all remaining candidate cells in an adjacent column or color zone, that square is invalid.
• Place a cross on the invalid tile immediately to force the cat into the alternate square of the sector.

Eliminating impossible squares prevents dead-end grid states and lets you finish Level 37 with zero mistakes and no need for hints or undos.
