As a method of getting people to buy your 99c game, offering them a $10 iTunes gift certificate would certainly seem to grab the attention.

Of course, developer Softmines - bizarrely part of an Indian real estate group - isn't handing out the dosh for no reason.

In order to gain that $9.01 profit, you'll have to

1. Write a review about its game - Bloody Hell - on the App Store on its launch day, August 10

2. Like Softmines' Facebook page and post the following on your wall "I will receive a $10 iTunes gift card by buying Bloody Hell for iPhone @softmines $0.99",

or

2.1 Follow Softmines on Twitter and re-tweet the following post to their followers: "Follow & RT @softmines to receive a $10 iTunes gift card by buying Bloody Hell for iPhone for $0.99".

Then you have to email at promotions@softmines.com with the following details: Facebook ID/URL or twitter ID/URL and your iTunes nickname.

The promotion is only for US residents.

In addition, the person who writes the most helpful iTunes review will win an iPod touch, as will the player with the highest game score on August 31.

You can find full details of the promotion here.
