Big Brain Games consists of six games in total; Echo, an audio memory game, Fallacy, a logic game, NovaSweeper, which is Mine Sweeper with nobs and bells, Reaction, a fantastic little logic game (reminds me, for some reason, of the classic e-motion for you old timers out there) , Remembrance the classic card game (turn them up to match etc) and of course what brain training application would be complete without Sudoku!? 

The games are all pretty good; I especially like Fallacy and Remembrance which keep me entertained for longer stretches of time (not being natural Sudoku player, ie. I'm number retarded) but all the titles are great efforts which look and sound great. The presentation of this game is nothing short of immaculate, for mini games the whole atmosphere (and the bizarre random duck) really draw you in from the get go. Which in SGR's book, is a very good thing!
