A Monte Carlo Monopoly simulation I wrote in 2005.

Simulates a number of games of Monopoly, considering all movement-related cards and rules. Always pays to get out of jail.

Example:

$ ./monopoly -h
usage: ./monopoly [-g <games>] [-l <length>] [-t|-T] [-h]
-t: show only total counts
-T: show only land counts
$ ./monopoly -g 10000000
