From Michalis Nicolaides:
BubblePop is a fun and addictive bubble pop game to entertain children and at the same time make them smarter. As I watch people playing, I noticed that at first they just click the bubbles but of course unless they are very lucky they fail. The second time they do the same but they are more careful. After few times they create a plan to finish the game successfully. It is not chess but it is a good and funny way to make you think before you act. It runs on any system that has .NET Framework 4 (system requirement), Windows XP, Vista, 7 and 8, on both 32bit and 64bit versions. BubblePop is freeware (you can use it for free) and portable (no installation needed).
