Word Game Boggle Flash
Boggle is a challenging word game for kids and parents. I've got Boggle Flash (see picture) and was hooked on it. I don't think it's hard to get one; I purchased mine at Sogo.
It's a fast-paced game and has more than one play method. Basically, you put as many 3-, 4- or 5-letter words together as fast as you can before your time runs out based on the letters shown on the electronic tiles. You can earn 5 more seconds as you form each 5-letter word.
You can download Boggle on the App Store. But I still prefer Boggle Flash, because I like to shuffle the electronic tiles around, which seems to add excitement.
