Meowdoku Level 91 Walkthrough

hard 8 colors

Meowdoku Level 91 opens from the lower-right side even though the last empty square sits in the upper-left. Row seven, column six and row eight, column eight separate the purple slab from the orange belt, which then lets row four, column five, row six, column four, row five, column two, and the final green top-lane cat on row one, column three fall into place.

Board Notes

Layout: This 8x8 board uses a green upper-left block, a cyan top river, a pink right rail, a yellow pocket on row two, a sky-blue left column, an orange center belt, a rose row-seven strip, and a purple lower-right slab. The puzzle starts with fixed cats on row two, column seven and row three, column one.
Goal: The board releases from the lower-right side rather than the top. Row seven, column six and row eight, column eight have to settle before the orange middle can take row six, column four and the cyan bridge can finally claim row four, column five.
Opening: Keep the fixed cats on row two, column seven and row three, column one, then place the rose strip cat on row seven, column six before the purple corner cat on row eight, column eight. That pair is what turns the orange belt and cyan bridge into clean lanes.
Danger Zone: Row one, column three looks almost solved from the start, but the top green lane still shares diagonals with the cyan bridge until row four, column five and row six, column four are both fixed.
Mechanics: Level 91 is a delayed top-lane board where the last upper-left cat is the consequence of solving the lower-right corner first.

Quick Tips for Meowdoku Level 91 (spoiler-free)

If the board's last empty square is on the top row, check whether the lower-right corner actually controls it before you commit there.
With 8 colors in play, clear the pair with the fewest blockers first so the board opens up instead of tightening.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.
