Thousand Heroes (or 1000 Heroz) is a Pocket Gamer Bronze Award-nabbing platformer that tasks you with racing to the end of an all-new stage every single day.

Your aim in Tiny Robots is to protect three 'seeds of life' from waves of vicious alien invaders by shooting them out of the sky with your range of weaponry.

You control your vehicle of destruction by tilting your device to move from side to side, and tapping your screen to fire shots. Keeping your finger pressed down for a few seconds will release a charged blast.

Solitaire, as you all probably know, is a classic card game that sees you attempt to group all cards of a similar suit in ascending order.

It might not sound as riveting as shooting aliens in the face, but it can be quite addictive.
