What is a double up slot?

Double up slot is a slot machine game that as its feature offers players to double up or gamble the winnings obtained by turning the reels.

Double up slot can be an online slot game that we play at the gambling platforms from the list of best online casinos in NZ or an offline slot machine that is played in land-based casinos. This function or feature appears after you win slots in the main game.

Players can choose to gamble their winnings or to collect and keep on with spinning reels. If they choose the gamble or double up a feature they will be redirected to a different screen where they can start doubling up.

How does the gamble feature work?

Slots with gamble feature offers players a chance to double their winnings with a 50/50 chance where the winnings are doubled or quadrupled if you hit. If you lose, that is, if you incorrectly predict the next outcome, all your winnings are lost.

The classic double-up feature uses a common deck of cards where it offers the player to guess whether the next card drawn from the deck will be red or black, what the suit will be, and whether the card will be higher or lower.

After each win, players have the option to collect or continue to double.
