Earn diamonds by playing the Cashback Troopers game in the ShopBack app. Exchange 150 diamonds for a prize. The prizes:

$20 Instant Win cashback

$5 Instant Win cashback

$2 Instant Win cashback

$1 Instant Win cashback

$0.50 Instant Win cashback

Prize Draw entry for $1,000 cashback (Prize draw excludes SA participants)

Additional lives for extra plays (a chance to earn more diamonds)

$1,000 prize draw is not valid in SA. Instant win cashback prizes are valid Australia wide.

Cashback Troopers was previously submitted as a deal last November but has long expired. The prizes are different this time. I'm not sure how many instant win cashback prizes are available or how long the game will remain active for. Edit: Current round closed April 30 at 11:59 pm.

Mod note: As this game now includes a prize draw entry as one of the prizes, it is no longer a game with a guaranteed win. The moderators have discussed this and decided to move it to the competition section for consistency.
