who can help me out that i just can't play the games, some playing software should be installed first?

you will need adobe Flash player. Please download it from here http://www.adobe.com/products/flashplayer/

It will take only a few minutes to install

Good Luck :)

thanks, i will get one soon

i can play now, wow, these games are very funny and great!

Thats great :) , you should also try to submit your score.
