Binaryjoy has launched a contest where anybody can win the entire Ricochet series of games. The rules are quite simple: first you have to subscribe to their main site feed. Then, some time in the next week or so, a question or a riddle will be posted in the feed. The first person to send in the correct answer will get the entire Ricochet series and 4 persons can win a copy of Ricochet Infinity.
Check it out in case you want to have a chance to win stuff.
