It's just like a slot contest.

You can play as much as you can but tried to chase and apply to the high multiplier. It's really simple:
- Play
- Get the most multiplier you can get
- Then, claim your bonus of 10%

Always send the most higher multiplier you can get until you stoped the gamble, since you only claim once so you must chasing the most high multiplier you can get to claim 10% because you will get more money.
