Step01—Meet the board
This is KenKen.
A 4×4 grid divided by thick borders into cages. Each cage has a target number and an arithmetic operation. Fill digits 1–4 so each row and column contains each digit exactly once.

Cage digits combine via operation to equal target
Logic only — no guessing required
