The document describes a programming contest hosted by Klarna in 2011 focused on developing Reversi bots, a GUI to watch bots battle, and improving the Erlang servers handling the battles. Contestants were challenged to create a powerful Reversi playing bot using any programming language that could be run on Klarna's Linux machines. They were also tasked with building a beautiful RESTful GUI in either Chrome or Firefox to view bot games in real time, and help optimize the scalability of Klarna's Erlang game servers using OTP. Prizes included various iPod models, with the deadline for submissions being March 30th, 2011.

1. Klarna Programming Contest
2011
Reversi Bots Galore!

2. Contest Goals
• Create a bot that plays Reversi over the
net.
• Or create a nice RESTful GUI to watch the
bots battle it out.
• Or try your hands at OTP and improve the
servers handling the battling.

3. Bot creation
We at Klarna love hacks, beautiful code and clever
algorithms. Therefore we want You to create the best
Reversi playing bot possible.
• You can use any language (that we can run on our linux machines)
• Judges will look both on how well the bot plays,
and clever ideas used in making it.
• Simple clients in Erlang will be provided to get you
started.

4. GUI creation
The web needs to be beautified! Show of your talent
in creating a killer RESTful GUI to watch the bots
playing in real time.
• The GUI should be able to run in either Chrome or
Firefox on Linux.
• It should talk REST with JSON objects.
• Of course it should be drop dead beautiful.

5. Erlang plumbing
Having tons of bots hammering our game servers will
probably cause some meltdowns.
• Help us improve it! Code will be available on
github.com
• Try out making scalable servers with OTP.

6. Prizes
1. Ipad
2. Ipod touch
3. Ipod nano
4-5. Ipod shuffle
