I'd Tap That|不限時間玩解謎App
As my 8-year-old son said, "I can't eat now, I'm glued on this game."
It's a chain reaction style game that gives you or your kids hours of mindless fun. It is short game so you can play while standing in line at store.
This game was written at the request of my wife and a couple of her friends who used to play a similar game online that they were all addicted to years ago.
