You should ask more details about the wagering requirement rules of your deposit first if you are going to make a deposit.
I'm just worrying that not all games are counted toward the wagering requirement, but if all games are counted then I think you can wager 5x without losing much by playing the dice game.
However if not all games are counted, I suggest you not to make deposit to withdraw your winning from their promotions as it might be something not worth.
The decision is on your hand ofc, if you think that it is worth the risk to deposit and wager it 5x to withdraw your winning, you can go.
