Cairo Corridor is a two player game where players alternate playing pentagons until a "corridor" is established. A corridor is a group of empty pentagons that connect all 4 sides of the board. Playing such that there are no corridors able to be traced is illegal. The game ends when no more pentagons can be played in the corridor's area legally. The winner is the player with the most number of pentagons next to the corridor. In case of tie, the last player to play is the loser.

In this implementation, yellow pentagons are how illegal moves are denoted. If you think about the rules a little bit, you will come to understand that these illegal pentagons will eventually form the final corridor. Pentagons with blue borders are scoring pentagons because they are next to illegal moves (which are the final corridor).
