Duopento

Each player receives a set of twelve tiles. Alternately, you have to place the stones on the board in such a way that you form as large a contiguous area of a color as possible. At the same time, one should prevent the opponent from doing the same. The tactic: to define as large areas as possible, in which only your own pentominos fit. The whole thing is finished when no one is able to accommodate one of his pentominos on the board.
