- There are some special additional Bonus Games available on a lot of Online Slot Machines.
- Slot Machine Gamble Rounds are pure chance and luck Features that might reward you with some extra coins.
- There's Hi-Lo and Double-Up Games available in Slot Gamble Round Bonus Games.
Another type of Bonus Round is pure 50/50 gambling for extra coins to boost your balance. In Slot Machine Gamble Rounds, you need to predict the colour of the next card you are going to turn up. If you make the correct choice, you get another turn and so it continues until you get one wrong. This is known as the double up or gamble round and can be found in addition to Bonus Rounds, or sometimes instead. Some Slots also have the option to guess the suit of the card drawn. If guessed correctly, it will quadruple your total bet.
There's either a 1 in 4 chance of winning or a 50/50 chance in Double Up / Hi-Lo / Gamble Bonus Rounds.
