UNO Blast allows you to steal Coins from your opponent.

Up to 3 rounds, each round you choose 1 of 3 random Cards and insert it into the Card Blaster.

Each inserted Card adds a multiplier to the final Coin payout. At the end of UNO Blast, all Card multipliers are combined to determine the total amount of Coins stolen.

However, each Card also carries a chance to trigger a Blast. If a Blast occurs, UNO Blast ends and you cash out with the multipliers earned up to that point.
