About All Star Knockout Slot

The game has 5 reels and 4 rows. On the 20 positions, you can form combinations of 3 or more matching symbols on any of the 20 fixed pay-lines and win. You can choose wagers in the range of 0.20 to 400 credits per spin. The RTP of the slot is 96.09%, while its volatility is low to medium.

All Stars Knockout offers two extra features and a Gamble option. The latter is a shortcut to the free spins for the displayed price. On any losing spin, you can win unlimited free rounds with up to 3 winning rounds. This is the Random Bonus.

The central attraction is the All Stars Knockout Bonus. With it, you collect star symbols and once any of the symbols gets 5 stars, you win 5 free spins. The respective symbol is removed that symbol from the game. The jackpot in the slot is 4,500 times your stake.

All Star Knockout Design

The design of the slot is rather basic but perfect for the theme and features. The background of the playing area is blue with shadows of stars and white illuminating effect on it. The symbols include all kinds of fruit, 3 types of single 7s, stars and a game logo – a KO icon.

Below the grid is the Award Board with symbols and star positions next to each one. The free spins take place on a fiery orange and red background. There are stars too and the same illuminating effect but in yellow. The layout is intuitive and convenient. You will see the gamble option and the stake sizes on the left, the spin and auto-spin button on the right of the reels.

During free spins, you have only the multiplier displayed on the left. The main menu drop-down is at the uppermost left corner of the screen. You will relish in a traditional, jazzy, 70s inspired soundtrack during the rounds.

All Star Knockout Gameplay

The symbols that you will land on the reels are 8 classic ones. There are the familiar lemons, oranges, plums, cherries as well as blue, white and red 7s. The most lucratively paying symbol of all is the KO icon – this is the game logo. Land 3, 4 or 5 symbols on a line to win 1.5, 3 or 5 times your stake, respectively. There are no wilds or scatters in the game.

All Star Knockout Features & Bonuses

Two features that keep the gameplay more interesting are two. These are the Random Bonus and the All Star Knockout Bonus. After any losing spin, you can have the Random Bonus triggered, which will give you up to 3 win spins. These are many free spins with up to 3 winning ones, which guarantee payouts. The spins will continue as long as you score a winning round.

As the game’s name suggests, your aim is collecting stars to knock out symbols. Whenever you land a star symbol, it gets collected. The star is placed at a random position next to one of the symbols in the Award Board at the bottom of the screen. When you collect a total of 5 stars next to any of the symbols, you trigger the All Star Knockout Bonus. It gives you 5 free spins, each of which has a random multiplier of x2, x3, x4 or x5 applied on every win.

Star symbols will continue to land during free spins. So, you have the chance to collect 5 stars next to another symbol. This would increase the number of free spins by adding 2 more. What makes the game even more intriguing is that every time a symbol collects 5 stars, it is removed from the game. This symbol won’t appear on the reels anymore. It would be an advantage if the symbol is of the low-value ones or work against you if it is one of the premiums.

There is an important thing you need to be aware of and keep in mind. If you change the bet level in the middle of a session, the star collection starts from the beginning. Don’t worry though since your achieved progress is saved. If you return to the same bet level, you will continue from where you left off.

Players have another option – a shortcut to free spins. This is not a buy option, but rather a Gamble game – you will spin the needle to try your luck. The price this will cost you depends on the bet level you play on and the number of stars you have collected so far.

The Conclusion

All Star Knockout is a retro fruit machine inspired slot with a few nice twists and modifiers. The game offers profuse payouts of up to 4,500x stake, which regarding its volatility is great. Being a mixture of classic slots with unconventional features, the game can suit the needs of all kinds of punters. Wait for its release in March and test the slot in our free demo. If you are pleased with it, you can spin for real. For this purpose use any of the recommended online casinos offered in our website.
