Katamino Duo

From BoardGameGeek:

Katamino Duo – a.k.a., Katamini – is a junior version of Katamino, with two players competing on one game board divided into smaller spaces to fill all of the empty spaces first. The game is played over a number of rounds, with each round becoming progressively harder. Katamino Duo also works as a solitaire puzzle, with the solver trying to fit the pieces onto the playing area in different ways.
