Meowdoku Strategy: How to Solve Any Board Without Guessing

Meowdoku strategy is not a list of tricks. It is a small set of deduction patterns applied in a sensible order, and once you can recognise them you stop getting stuck. Here they are, roughly in the order you should reach for them.

Pattern one: the forced placement. A region with only one square that no X touches must take a cat there. A row with a single open square must take a cat there. A column, the same. These are free, they are always worth scanning for first, and on beginner boards they are usually the entire solve.

Pattern two: X cleanup. Every cat you place rules out its row, its column, the rest of its region, and all eight surrounding squares. Do that marking immediately, every time, without exception. Skipping it is the single most common reason a board feels stuck when it is not - the deduction is available, you just have not written it down.

Pattern three: the locked region. If every square a region can still use sits inside one row, then that row's cat must come from that region. You do not know which square yet, but you know the row is spoken for, so every other square in that row can be marked. The same reasoning works with columns, and it is the pattern that unlocks most intermediate boards.

Pattern four: line counting. Read two or three rows together and ask how many regions they can possibly be fed by. If three rows can only be served by three regions, those regions are used up by those rows, and every square those regions own outside the three rows can be marked. This is the pattern that separates intermediate from advanced play, because it produces information from a part of the board you were not looking at.

Pattern five: the bottleneck. When nothing else works, stop looking for cats and look for tightness. Which set of lines is fed by the fewest regions? Which region is pinned into the smallest number of columns? The tightest part of the board is where the next deduction lives, because that is where the constraints have the least room to move.

A practical loop for any board: scan for forced placements and take them all; mark the Xs each one creates; look for a locked region; if none, count lines; if that fails, find the bottleneck. Then start again, because every placement resets the board. The loop is not glamorous, but it is complete - a Meowdoku board that resists all five patterns is rare, and on those the answer is usually to restart and re-check your Xs rather than to guess.

The meta-rule underneath all of it: never place a cat you cannot justify. You have three hearts and no undo, and a guess does not just risk a heart, it also destroys your ability to trust the board. A wrong X costs a second. A wrong cat costs the run.
