Out of all the game based apps I have, this one takes the cake. It's chess, but the majority of your pieces and your opponents pieces are scrambled up or randomized, Giving you crazy possibilities like having 4-5 Queen's at one time, 5 castles, need I go on? The most gripping feature to this app however has to be the daily and weekly boards, and the good challenge it gives you. Needless to say I've competed score wise with friends, have a blast, and we shall for a while. Great app!
