Block

Twenty blocks move in a board of forty houses in order to block the movement of the other twenty of different color.
Initially each house is filled by one block; these are aggregated forming larger pieces that when moved to empty houses are divided into two smaller ones.
The same movement rules result in different paths when applied to the various sizes of pieces.
The blockade can be achieved by arresting opponent's pieces, obstruction of pathways, by isolation of single blocks and protection of terminal houses. All these actions can be fought by releasing pieces, clearing pathways, by rescuing isolated blocks and attacking blocks that impede movement termination.
A more strategic complexity is achieved with the four-player mode in teams of two; playing with half the blocks of his team each player has two opponents and one ally.
