Gamble Feature
After any reel win, you can take the win or gamble on one of 2 gamble wheels – one for cash and one for the chance to win a number of Free Spins. The spins can be gambled all the way up to 50 spins. During Spin Boost any mixed 7’s symbols that form part of a win will upgrade all the 7 symbols to the highest paying 7 symbol on any active win line.
