compared Blokus

This is the same style of play that BLOKUS. The pieces are less varied and some are in two copies in Callisto.
In Blockade, our pieces touch at the corners, in Callisto, our pieces are touching by a "side".
With Blokus, the game 3 player is not practical. You have to play 4 to enjoy the game.
With Callisto, the game remains balanced which can be 2, 3 or 4 players. There must be, depending on the number of players, a card under the transparent plastic base that changes the size of the board. This is the only point where Callisto has the advantage over Blokus.
