Here in the UK I'm pretty sure that everyone knows the game Simon which has been around for donkeys years. I have no idea though if it has had as much fame internationally but if not it may do now with Simon Plus for BlackBerry 10 smartphones.

For those of you that have not played it before it is real simple - Simon has four colors and you just need to copy the sequence that he chooses. Of course, it is easy to start with but as the game progresses it will really get the old brain matter working.

The graphics and sound are kept basic but the app looks beautifully clean and crisp. With Scoreloop integration you can also see how your buddies have been getting on. I can't seem to get past level 12 but then again I'm not the brightest spark!

Simon Plus may well be the perfect companion for commuting so go grab it from BlackBerry World. It's a little gem.
