A nice fun game but the best bit is the speed! I have tried the World Mosaics series & as they went from 1 to 6 they got more & more sluggish whereas this "World Riddles: Seven Wonders" is really fast at downloading & moving on to the next level which made it all the more enjoyable! I have only played the hour trial so cannot say if the speed keeps up further on but this is definitely a game I will be buying.
