The Australians were the first to invent gamble slot machines that
allow you to double up your winnings, much like in video poker games. These gamble
feature slots quickly spread to other parts of the world and it did not take
long for online casinos software providers to launch similar games on line.
Australians call these machines "pokies" and they allow you to double
up your win as much as five times.
An attractive advantage of these gamble feature slots
games is that you are making a fixed odds bet when you double up. For example,
if the double up game gives you two options to shoose from, you have a 50%
chance to win and so on.
There are currently only two online slots that offer a double
up option or that gamble featur slot. These are both five reel, 9 pay line video slots with 45 coins max
bet (5 coins per line). They have a bonus round where you can win 15 free games
which can be re-activated unlimited times. These gamble feature slots are Thunderstruck and
Spring
Break from Microgaming.
The Double Up Gamble Feature Slots require you to choose different
combinations: Red / Black or Diamonds / Hearts / Clubs / Spades. They come in
denominations of between 1 cent and $1. Top jackpot is 10,000 coins or 30,000
coins on the free games.
As an example, lets have a look at the Thunderstruck online video
slot. The big jackpot is 10,000 coins and the second highest prize is 2000
coins. The chances of hitting either of these combinations are quite low.
However, there are many smaller prizes between 50 and 100 coins.
If you were to win 100 coins, move on to the gamble screen you
could turn this into a 1600 coin win if you are successful at the bonus game
twice. Gambles a third time and you can double up to 6400 coins.
Gamble feature slots, especially double up features, are a very
exciting way of increasing your winnings without having to hit large jackpots.
