It looks like some unconfirmed transactions maybe messed up the script. The transactions were unconfirmed because some bozo sends transactions without fees. If you are so cheap why would they play a game that can easily result in 100% loss? Maybe they are doing it on purpose looking for weaknesses.
Unfortunately Bitcoin has this issue with too long confirmation times, which is something really annoying in a game in which timing is crucial. Someone should consider creating a weeklyponzi in an altcoin with better confirmation times, like Doge or LTC.
