I like instant win games because I know immediately if I won or not :)
I was playing the new Kool Aid Instant Win game this morning and won a prize, a Kool Aid wireless speaker. Enter for your chance to win 1 of 8,000 great prizes! Prizes include wireless speakers, string backpacks, headphones, water bottles, basketball sets, sunglasses, and more. I won on my second day of play so pretty happy about that.
