4NumGuess: This bizarre number guessing game does not come with instructions, and has to be played in side-view mode. Numbers need to be entered using the on screen display, rather than the keypad, which may seem an odd decision but it means that it is fully compatible with machines without one.

Amazed: A 2 dimensional maze game in which you have to guide the ball around by tilting the phone. Although simple, this game features some of the best use of the accelerometer in an Android game to date.

Asquare: If shape matching games are what floats your boat, then you might want to download Asquare. Simply match three shapes by swapping one or two at a time. The better your matches per turn ratio, the higher your score.

Backgammon: If ever there was an example of a game not suited to using the touchscreen interface, it is Backgammon. Although the graphics and computer opponent are decent enough, it is too easy to drop your counter in the wrong place.

Bonsai Blast - Arrgh! You are being confronted by a never ending stream of coloured balls. What can you possibly to save yourself? Shoot back with your own coloured balls, of course! This great-looking game is marred by the inaccuracy of the touch screen control, particularly if you have chunky fingers.

Brain Genius Deluxe - Whether you are already smart and want to stay that way, or you want to improve your IQ, then there is no substitute for a proper suite of brain training games, including SuDoku, Sliding Puzzle, Crosspix and Jigsaw. You can use the accelerometer and touch screen for most of the games, but after a while you will probably end up preferring the joystick.

Bubble Bash demo - This cute-looking game involves shooting coloured balls at other coloured balls, in order to make them disappear. The aiming can be difficult using the touch screen, but it is otherwise a fun game.
