Logic puzzle
Treasure Plotter
A pirate, a map, and a rule you can trust: every colored region holds exactly one treasure, and so does every row and every column.
Read the map
The adventure starts with easy treasure maps, so the rules settle in quickly. Later puzzles ask you to study the map, cross out impossible squares, and place every treasure where it has to be.
Each map is a new brain teaser. The rules stay simple. The deduction does not.
