Pentagon is a two-player game where players take turns to place tiles onto a grid. The tiles may be pushed onto the grid only from the edges, and only if there is room left for any existing tiles to be pushed along the specified row or column.
The two players may be situated at the local computer or at remote computers with communication via a TCP connection (e.g. on the internet). Players can type messages to each other using a panel that opens up at the bottom of the game window when a connection is open.
Pentagon scored 5th place in the 1999 GEM game competition organised by Magic online and Place to be!
