Meowdoku Tips and Tricks
Use color regions before rows
A region that only has a few cells is usually more informative than a row with many possible cells. Mark those region candidates first, then see which rows and columns they affect.
Treat adjacency as a removal rule
Every placed cat removes the eight surrounding cells from consideration. Even a candidate that is not final yet can help you see which neighboring cells cannot both be used.
Scan columns after each row decision
Because each column gets exactly one cat, a row placement is also a column placement. After you narrow a row to one or two candidates, check whether either column is already claimed by another forced region.
Watch for paired regions
Two color regions can sometimes occupy the same two rows or columns. If one region takes the first column, the other may be forced into the second.
Use the Solver as a Check
The screenshot solver is most useful after you have tried the board yourself. It can confirm the final cat positions and show whether a board has one clear answer.
If your manual board copy is not solving, check that every color region is painted correctly and that the board size matches the screenshot.
