Blocker is a two-player game in which players attempt to cover the most area on the board while blocking their opponent from covering their area.
On a player's first turn, their first piece must cover one of the white starting squares. After that, pieces are placed corner-to-corner: at least one corner must touch a corner of another piece belonging to the same player. Two pieces of the same color cannot touch along an edge.
Player A always goes first. The game ends when one player cannot place any more tiles and the other player has a higher score, or when neither player can place any more tiles. The score is the number of squares covered on the board.
You may need to move pieces around in the pile to uncover the piece you want to play. To play against the computer, click the Auto Move button when it is the computer's turn.
