Bonuses and a game like this
A 40x wagering requirement in three days means betting forty times the bonus in 72 hours. On a game as volatile as Fire in the Hole 4, that is a lot of spins on a balance that can drop fast. If you want calm play, skip the bonus and keep the right to withdraw your deposit after one turnover.
