Trinudo

Trinudo is a logic puzzle. It is played on a rectangular grid. Some cells of the grid start containing numbers, referred to as "givens". The goal is to divide the grid into blocks of either one, two or three cells. Blocks of the same size must not be orthogonally adjacent. Each given number represents the size of the block to which it belongs.
