Gameloft have just introduced a new scheme called Gameloft club. Available for UK android users only, it lets you download one game per month for only 0.99p.

To activate a Gameloft Club subscription, simply visit www.gameloft.co.uk on your Android HD device and click the “Club Buy 99p” link next to the game of your choice – there is a whole range to choose from
They have also created a contest in the hope of getting people signed up. If you register for their Gameloft Club between now and midnight Monday 29th August, you will be in with a chance of winning a new LG Optimus 3D.
