Just like fruit machines such as Lightning Joker, All Star Knockout Ultra Gamble slot sites offer you some exciting bonuses, focussed around the All Star Knockout and Ultra Gamble features:

All Star free spins


Filling-up an award board during regular spins, with five stars, triggers the All Star Knockout bonus. The All Star Bonus gives your five free spins, with two bonus spins for any other award board completed during the bonus. The triggering award board and those completed during the bonus, makes the symbol ‘knock off’ the reels during the bonus, boosting the odds of landing winning combos. The bonus round has a random multiplier of x2, x3, x4 or x5 for combined bonus wins at the end of the round.

All Star Ultra GambleULTRA GAMBLE

Clicking on Gamble gives you the chance to spin a dial and gamble to instantly enter the All Star Knockout Bonus game. You can choose to gamble for 1, 3, or 5 stars if offered – with each option having a higher bet amount and being more daring!


The award board has five spots for each of the eight award symbols ( such as Red 7 or Silver 7), which randomly fill-up with gold stars as you spin the reels during the base game and bonus. The stars don’t reset after regular spins – boosting the chances of filling-up the boards and getting rewards.


At the start of the bonus game or whenever the award board is completely empty, you get awarded 12 random bonus stars to boost winning chances.


After losing a spin, the random bonus can be triggered. You’ll get a random number of ‘Win Spins’ with up to three per round; these spins guarantee you a win and you can also trigger the All Stark Knockout bonus.

If the bonuses on All Star Knockout Ultra Gamble slot seem complicated, the main thing to decide, is whether to place a regular spin, or up-the-ante and click the Ultra Gamble button to directly enter the bonus round – it all depends on your budget and how daring you’re feeling.
