Kumi: Number Logic Puzzle

Kumi is a logic puzzle with numbers: simple to learn, deeply satisfying to master. HOW IT WORKS Divide the whole grid into groups of neighbouring cells. Each group has the number of cells shown, and its digits add up to the total. A clue like ▢▢ = 10 says it all: no need to read any particular language. Every puzzle has exactly one solution.
