The maximum bet limit available is $100 per spin, and the biggest payout you can achieve is 4,570x your stake. There's no one way to earn it, instead trigger enough cascades, and your wins will add up quickly. For the chance at the biggest payouts, fill the quantum leap meter to unlock the Gargantoon feature.


To start your galactic adventure, choose your bet size and then click on the green spin button on the right-hand side. The yellow spin button lets you set up autoplay. On the left side, you'll see your win history. With so many symbols on the screen at once, it can be hard to keep track of your winning payouts. So here, you can easily see which symbols matched on the reels.

You need to match at least five symbols in a cluster, which is formed when the same symbols are touching horizontally or vertically.

Coin sizes

The minimum bet per spin is $0.20, and the maximum bet size is $100. There are no paylines, which instead uses the cluster mechanic.


There are 8 regular symbols. The high paying symbols are cute aliens with two eyes. The most valuable ones you'll want to see on the reels is the purple alien, which pays between 1x-750x your total bet. The second most valuable symbol is the green alien, and he can pay between 0.80x-300x. The yellow alien has a payout range of 0.60x-150x, and the blue two-eyed alien can pay 0.50x-75x.

The lower paying symbols only have one eye, but during each spin, one type will be designated as a fluctuating symbol. If any of these fluctuating symbols become part of a winning cluster, they'll leave behind two glowing orb wild symbols, which can take the place of other symbols to earn more payouts.

Quantum Leap

Each win charges up the quantum meter. After winning with 25 symbols, you'll unlock the next stage of the meter and receive a quantum feature, which is then used during a no-win spin. You can have up to 4 quantum features stacked up and ready to use.

Implosion - Changes 3-6 regular symbols into wilds, while destroying adjacent aliens.

Incision - Drops a wild onto the middle symbol, creates two diagonal lines, which then clone a random symbol and place it along the incision line.

Demolition - Wipes out all one-eyed symbols.

Alteration - Randomly chooses a one-eyed symbol and transforms all matching symbols into another alien.

Get to the end of the meter, and you'll unlock Gargantoon. He'll jump onto the reels as a 3x3 symbol and acts as a wild. Then he'll divide into two 2x2 symbols, and finally nine individual wild symbols. With each transformation, new symbols will cascade down onto the reels.

Wild Symbol

There are no wilds that drop onto the reels with each spin. Instead, during any non-win spin, Gargantoon (the big evil alien on the right) may drop 4-8 wilds onto the grid.
