Super Hexagon is a game on my top list of apps right now. It's my go to game for quick game play and killing time. It's a simple game but you can really get yourself riled up, making you want to play it even more. The graphics are also awesome, complete with awesome sound effects too. All you have to do is crank up the volume and play.
The name of the game is simple. You're a little triangle, slap bang in the middle of the screen and hexagon walls start closing in on you. Some walls are gone and that's the gap you have to get yourself through and a maze like fashion. That's it but trust me you'll be hooked. From the simple fact that you want to beat your previous time, you'll be playing this repeatedly and may find yourself cursing at your BlackBerry from time to time. It definitely is an amazing game if you like this sort of thing.
Check out the quick game play demo above. If it tickles your fancy, you can get it from BlackBerry World for $2.99/£2.00. Available for the Z10, Q10 and Q5.
