Lean Pokeris a one day event for programmers where teams of 2-5 people develop a poker robot in any of the supported languages. Every few seconds the robots are playing rounds of Texas Hold'em Poker. To finish first at the end of the day the team needs to make sure that their robot collects more points than other bots. The main goal is not to win, but to learn. In this simulated environment teams need to deliver value in short time frames, which is a great opportunity to experiment with agile and lean practices without risks.
Best participants get a Lean Poker T-Shirt at the end of the day that I illustrated.
