It seems like there are a lot of these in the app store. I have tried Brain Toot (stupid name, but a great game, there are like 15 different ones and in a regular game, it fives you five random ones, one from each category) and Brain Challenge (more complex, I need to explore it more). There was also: Brain Surge (tried the lite version and did not care for it much) Braineous (expensive!) Brain Jogging (looks pretty good and only 0.99 so I am tempted) Fizz Brain (not as many games as the other ones, only 4 or 5) Train Your Brain (another I am considering, looks pretty good) Maybe some others too... So, which of these games have you tried? Which is your favourite? I am more into the pick and and play kind e.g. every time you say go it gives you three random games. I am less into the ones where you have to play some kind of epic quest and 'unlock' things.
