Multi-Colored Robot Symbols
This is a new slot from software developer CT Interactive, the online gaming arm of the CT Gaming Group.
Play the Doctor Winstein Buy Bonus slot online to enjoy a sci-fi themed slot with fantastic visuals. Symbols include various colorful robot characters and a brain covered with electrodes. The game board is designed to look like a scientist’s lab with several pipes, tubes and cogs.
Hit the Red Button
Betting options in the Doctor Winstein Buy Bonus slot machine range from 0.3 to 6.
With the cascading reels mechanic, winning symbols disappear and are replaced by symbols from above. This makes it easier to score big combination wins on a single spin.
Wilds can replace all symbols except Red Buttons and multiplier symbols.
Collecting three or more Red Button scatter symbols will trigger 15 free spins. Red Buttons pay out at 5x, 25x and 100x for landing three, four or five. You will be awarded a further 15 free spins by landing three additional Red Buttons.
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!
The Doctor Winstein Buy Bonus slot machine has 95.58% RTP and high volatility.
