Multiplier symbols with values of between 2x and 100x can appear during free spins. When several appear at once, the total of all values is used to multiply your winnings.

There is also a gamble feature called Double-Up in the Doctor Winstein Buy Bonus online slot. The option is available after making a win of 10x. You can double your winnings by guessing the color of a face-down playing card. Guess the correct suit and your win will be quadrupled!
