Wordfued
Wordfeud, developed by Bertheussen IT, is a cross-platform multiplayer puzzle game. Come up with bigger and better words, challenge friends or random opponents, and play up to 30 separate games simultaneously.
It is pretty much like scrabble for your iPhone and Android. It's played on a 15x15 board with virtual tiles offering double or triple letter scores on the individual letters or the whole word if you cover them up. Just like the old board game you play one word from your seven letter tiles, refill your rack with letters from a tile pool as you use them and then it's your opponent's turn. When the pool is empty and there are no tiles for making words, the highest score wins.
