Meowdoku!! Golden Fish Challenge Guide (After Level 54)

To solve the Golden Fish Challenge bonus stage between Level 54 and Level 55 in Meowdoku!! without mistakes, solve the board from the most restricted perimeter zones inward. Every valid cat placement must fulfill four simultaneous rules:

• Exactly one cat per horizontal row
• Exactly one cat per vertical column
• Exactly one cat per designated color zone
• No cats touching horizontally, vertically, or diagonally (an 8-tile buffer zone around every cat)

Because mistakes are limited, mark empty cells with crosses to eliminate invalid candidates before tapping to place a cat.

Step 1: Scan Small Corner Zones and Confined Lines

Begin by locating the smallest color shapes on the board, specifically clusters consisting of only two or three tiles along the borders or in corners:

1. Check for line-locked color zones: If a color territory is confined entirely within a single row or column, that line's cat must sit inside that specific shape. Cross out every other cell in that row or column outside that color zone.
2. Find corner eliminations: Confining a line frequently reduces adjacent corner color zones down to a single legal tile.
3. Lock in guaranteed placements: Place your first cats only in zones that have been reduced to one legal tile.

Step 2: Cross Out the 8-Tile Adjacency Buffer

The primary cause of failed runs on the Golden Fish board is violating the diagonal adjacency restriction. Whenever you confirm a cat placement, immediately mark off all neighboring tiles:

• Outer walls: A placement against a border invalidates three to five surrounding cells.
• Open grid: A cat placed away from the edge invalidates all eight surrounding cells across rows, columns, and diagonal corners.
• Adjacent shapes: Crossing out surrounding tiles frequently cuts off corners of neighboring color regions, collapsing wider multi-tile shapes into obvious single-tile choices.

Marking dead cells immediately prevents accidental taps and clarifies the remaining valid territory across adjacent color zones.

Step 3: Solve Mid-Grid Intersections by Line Elimination

After securing corner placements, the remaining open areas form wide, irregular color regions across the center of the board. Resolve these using row and column cross-referencing:

1. Pick an open row or column that still needs a cat.
2. Check the color territories intersecting that line.
3. If all intersecting color territories except one already contain a placed cat elsewhere on the grid, cross out the cells in the already-satisfied zones.
4. Place the cat in the remaining open tile belonging to the unfulfilled color zone.

Using line elimination bypasses the need to guess or test complex multi-cell branches.

Step 4: Verify the Final Placements

Before tapping the final two to three tiles, verify that your remaining candidates meet all grid conditions:

• Row and column check: Ensure each line from top to bottom and left to right contains exactly one placement.
• Diagonal check: Confirm that no two remaining candidates sit diagonally adjacent across grid seams.
• Color check: Verify that every color territory contains precisely one cat.

Once confirmed, place the remaining cats to finish the Golden Fish Challenge with zero mistakes and unlock Level 55.
