The PyWeek challenge:

1. Invites entrants to write a game in one week from scratch either as an individual or in a team,
2. Is intended to be challenging and fun,
3. Will hopefully increase the public body of game tools, code and expertise,
4. Will let a lot of people actually finish a game, and
5. May inspire new projects (with ready made teams!)

The dates of this challenge are are 00:00 UTC Feb. 28, 2016 to 00:00 UTC March 6, 2016.
