Coin Size:

First, you select the coin size - this will control the amount you wager on each line. The coin size is important because the amount you win is based on a multiple of your coin size - the larger the coin size, the more you could win. Simply click on the + or - buttons beside the coin size display to toggle through the different coin sizes.

Win Lines:

You can now select the number of lines you want to bet on. Lines are coloured and appear across the reels. You can bet on up to 20 win lines with Double Bubble. The more win lines you pick the more expensive each spin will be but the better your chances of winning on any individual spin are.

There are three ways to pick how many lines you want to play:

  • Click BET ONE to add another line. If you click past the maximum it will return to one.
  • Click on the coloured numbers at the side of the reels.
  • Click BET MAX to select the max lines and automatically start the reels spinning.

Betting on a lot of lines increases your chance of winning on any individual spin, though it won't affect the payout which is based on the coin size you have chosen.

Wild Symbols:

The Double Bubble symbol is Wild, like a Joker in cards, so it can substitute for any other symbol - apart from the bonus symbol - to complete winning combinations. And if you can land 5 Double Bubble Wild symbols along a pay line you'll scoop the max 20,000 x your coin size payout!

Bubble Line Win:

If any of the symbols appears inside a bubble, it's placed in the 2nd win area along the Bubble Line. If the symbols that appear in this 2nd area make a winning combo, that combo is multiplied by the number of lines wagered on. So if you bet on all 20 lines you get x 22 win.

Pop the Bubble Bonus Game:

Three Bonus symbols appearing anywhere on reels 1, 3 and 5 will initiate the Bubble Bonus round.

You'll be presented with 3 bubbles and asked to choose just one. If it pops to reveal a random coin multiplier you'll win it!

Formal Game Rules:

DOUBLE BUBBLE is a five reel, twenty line slot with bonus game and special scatter feature.

The active coin size is shown in the bottom left of the play screen and may be adjusted using the + and - buttons. You may bet up to twenty lines on each spin by using BET ONE to change the number of lines or pressing BET MAX to bet the maximum number of lines.

The game is commenced by pressing SPIN or BET MAX and this action being registered on our servers. This will cause the bet indicated on screen to be placed. Once the game has been commenced the game cannot be discontinued and the bet amount will be deducted from your account.

Each spin is completely random and independent. It is not affected by previous spins, or the start position of the reels. Each reel is independent and is not affected by any other reel.

Wins are paid in accordance with the pay table. The amounts shown in the pay table are coin multipliers not currency amounts and multiply the active coin size. Wins are scored from left to right starting on the leftmost reel. Wins are paid only on lines for which a bet has been made. Only one win, the highest win, is awarded on any single pay line. Wins on separate pay wins are added.

The "Double Bubble" symbol is wild and may substitute for any other symbol except the bonus game symbol.

Bonus Scatter feature: if symbols appear with a bubble outline around them they act as scatter symbols and are combined to form a "Bubble Line" displayed on the screen beneath the reels. If the symbols on the Bubble Line combine to match a win in the pay table then the win is multiplied by the bonus multiplier. The bonus multiplier is equal to the number of coins bet except when twenty coins are bet in which case the bonus multiplier is 22. The bonus multiplier is a coin multiplier and not a currency amount. Only one win, the highest win, is awarded on the Bubble Line.

If three "Bubble" bonus symbols appear on reels 1, 3 and 5 you are eligible for entry to the "Bubble Pop" bonus game and the bonus game will automatically commence.

The Bubble Pop bonus game provides a guaranteed chance of winning a cash prize. Wins shown in the bonus game are coin multipliers not currency amounts and multiply the active coin size.
