Every challenge names a Rainbet slot, a target multiplier and a minimum bet. Play that game on Rainbet under code JUSTINGAMBLES, bet at least the minimum, and if you hit the target multiplier you win the cash prize shown on the card.
Challenges are first to hit: the first player to land the multiplier and submit proof claims the prize, and the card then shows who claimed it. Take a screenshot of the winning spin — game, bet size and multiplier clearly visible — and submit it from the challenge card while signed in to your JustinGambles account.
Every submission is reviewed before the prize is paid. New challenges are added regularly across providers like Hacksaw Gaming, Pragmatic Play, Nolimit City and Backseat Gaming.
