Back in 2008, a group of poker players discovered a software glitch that affected 'Six-Pack' sit & gos on the popular online site Betfair Poker.

If all six players moved all-in on the very first hand, when all the chip stacks were even, the winner was awarded first place, but every other player received second-place money.

With Betfair’s offices closed overnight, the software bug went unnoticed — allowing coordinated players to exploit the flaw, quickly move up in stakes, and win hundreds of thousands of dollars. Some forum rumors suggested total losses reached as high as $1.7 million before Betfair intervened the following afternoon.

As soon as the loss was found, the sit & gos were shut down for a software upgrade and were inactive for over 24 hours.
