Game Rules

On every drop, any combination of 4+ matching symbols touching horizontally or vertically will result in a winning combination.

After the payout is made, all winning combination symbols will explode, allowing the symbols above them to cascade in.

Maximum Payout Cap

There is a maximum potential win cap of 5,000x your bet on the game. This is applied to an individual round but can include within it all original symbol payouts, cascade multipliers, Free Drops and the wheel within the single round.

Cascading Multiplier

A win multiplier is applied to, and increases with, every cascade. Wins can be very high but are limited to the maximum payout cap.

Free Drops Symbol & Free Drops

During Free Drops, every win will increase the cascading multiplier by 1. This cascading multiplier will continue to build with every win and will not reset until the end of the Free Drops session.

  • 4 matching free spins symbols awards 11 Free Drops.
  • 5 matching free spins symbols awards 13 Free Drops.
  • 6 matching free spins symbols awards 16 Free Drops.
  • 7+ matching free spins symbols awards 20 Free Drops.

Free Drops may also be awarded from a spin on the Jackpot Wheel game, upon powering up an element.

Bonus Symbol and Bonus Game

Matching a combination of bonus symbols will take a player to a galaxy of Starsigns. A player gets to pick 2–5 signs. The number of signs the player gets to pick is based on how many symbols they activated the bonus game with, shown in the table below. Each sign will reveal a cash value. The player wins the total accumulated value from their picks.

Symbols Matched Bonus Picks Awarded
4 2
5 3
6 4
7+ 5

Larger multipliers are available when the player enters the bonus game via a higher number of bonus symbols. Entering the bonus game with an active win multiplier will also increase all bonus values by the multiplier amount.

Comet Symbol

A matching combination of comets will cause a large explosion on the reels. Any symbols touching the comet symbol adjacently will be destroyed.

Symbols destroyed by a comet explosion will count towards unlocking Power Mode or add additional power to a meter during Power Mode.

Power Mode Symbol

There are 5 Power Meters that can be activated by completing or matching the corresponding number of symbols shown on the meter.

Each Power Meter leads to a distinct new galaxy, home to one of five elements.

Power up by matching symbols until it explodes. All symbols add power (except bonus and Free Drops symbols). Successfully defeating the boss will award the Jackpot Wheel feature.

Note: Game progression towards Power Mode features, and within Power Mode features, is saved and carried over to the next game, allowing players to continue their progress at a later time. However, game progression is tied to the stake used. This means a player can enter Power Mode by collecting symbols from gameplay with a stake of 1.00, but if they change their stake to 2.00 that game progress will be reset (or resumed to that of their last game played at that stake). After playing with a stake of 2.00, if the player decides to return to the previous stake of 1.00, their prior progress at that stake will be resumed (and their progress at 2.00 saved for later).

Jackpot Wheel Feature

Upon powering up an element this feature will activate. A 5-tier prize wheel consisting of Hyper, Super, Giant and Dwarf prizes along with Free Drops will present itself in front of the reels.

The player is granted 1 spin on the wheel. The available prizes grow larger in value per boss and are shown below:

Boss Hyper Super Giant Dwarf Free Drops
Boss 1 X4 - X8 X10 - X20 X50 X250 10
Boss 2 X4 - X8 X10 - X20 X100 X500 10, 12
Boss 3 X4 - X8 X10 - X20 X150 X1000 10, 12, 15
Boss 4 X4 - X8 X10 - X20 X200 X1500 10, 12, 15, 20
Boss 5 X4 - X8 X10 - X20 X250 X2000 10, 12, 15, 20
