i have been playing this game for six months,sorry to say but the only way i can get a decent brain score is by doing the same three tests on the brain age tests, not going to say what i get if i dont do this.dont understand how the reading scores are calculated, not much help from the game, everytime i yhink i do ok i get a rubbish score. maybe its an age thing i dont know.if you like achallenge or you and hubby are competetive could be fun or could cause world war three if you keep beating there scores.i also find the voice calculation test quite frustrating as sometimes it takes me quite a few attempts to get the game to register my answers.if you like sudoku this game has loads of sudoku puzzles ranging from easy to hard.all in all an okay game,have fun playing it.
