Like the Free Lotteries, the prizes for online games can be paid out due to the advertising space sold on each site. Never mind that though, just enjoy the smug feeling of entering the competitions and hopefully winning a prize.

Every site has been checked to make sure that prizes can be claimed internationally (your local laws permitting) unless otherwise stated. I've registered at each of the following sites to make sure everything runs smoothly, but if you do have any problems let me know.
