Reversi-5x5 games

There are 189,174,688,641 distinct games on a 5x5 sized board. Half of these games end with one of the 8 scores from 11:14 to 18:7, all of these scores resulting for 10.3 to 14.75 billion games. There are a lot more games that player 1 wins than games that player 2 wins.

My histograms have a maximum bin content of 2 billion events (32 bit integer), so I can't plot this without making some changes first.

The shortest games end after nine disks are played with scores of 13:0 (8 times), 12:1 (once), followed by games ending in 14:0 (once) and 6:8 (4 times).
