How to Play All Star Knockout slot online

All Star Knockout is a video slot that features 5 reels and 20 paylines across a 20 symbol matrix. All lines are always active on default.

You can bet in a pretty wide range: between 20 cents and 400 euro per spin.

The slot is provided with 8 basic symbols, bonus symbols, an accumulative bonus system, and free spins with prize options.

Paying combinations land on active lines, starting from the leftmost reel. Multiple wins are possible in the result of one spin.

Payoffs depend on the current bet and a multiplier. All money goes to the player's balance at the end of each spin – there is no chance to double it up.

Please read about bonuses, exceptions from the general rules, and other features of All Star Knockout below at Casinoz.

The key element of the classic design is stars. They land on the reels, shine at the bottom of the screen, and fly across the screen. The background music is pretty plain and repetitive. The animation is far from being spectacular.

All Star Knockout Symbols, Wild, Scatter

You will land such regular symbols as a logo, cherries, lemons, oranges, plums, as well as red, blue, white sevens. Same symbols may arrive in a stacked formation.

The only special symbol is:

  • Star (golden hexagonal star) is an accumulative symbol. It lands on all reels but doesn't pay. Stars move to so-called Award Boards, where they are stored until the bonus game begins. Please read more about that below in the review.

Wilds and scatters are not provided by the rules of All Star Knockout video slot.

All Star Knockout Bonus games

Let's discuss the bonus options:

  • Award Bonus – there is a screen with all 8 basic symbols and 5 boxes next to each below the reels. Every time a star lands on the screen, it randomly takes one of those boxes. The stars are accumulating until the player decides to change his bet. The bonus round begins when all boxes next to a particular symbol are full of stars.

Initially, the slot gifts you 12 stars randomly scattered by the boxes.

Moreover, each spin may trigger respins:

  • Random Bonus – first respin guarantees a winning combination. Each following respin rolls in a standard way. If it also brings a payoff, the feature goes on. Respins will be rolling until the first losing one.

And one more bonus option:

  • Low Stars Bonus – if at some point you have 4 or fewer stars in all boxes, a free respin begins. It guarantees some stars to land on the Award Board.

See Help for a detailed description of all bonus rounds.

All Star Knockout slot free spins

The main prize feature of All Star Knockout is free spins:

  • All Star Knockout Bonus – 5 free spins on the casino's money by the previous bet with an extra multiplier from x2 to x5. All symbols that have started the Award Bonus are removed from the screen. If you manage to complete other collections during free spins, these symbols disappear from the screen too. Moreover, it extends the feature to 2 free spins. You can get rid of up to 7 symbols during a session.

Free spins can be retriggered.


All Star Knockout doesn't feature progressive jackpots either from Northern Lights Studios or Yggdrasil Gaming.

Should You Play All Star Knockout Slot for Real Money?

We have an impression, this slot was designed for a narrow range of casino players. Conservative fans of classic video slots won't love it. Those who prefer spectacular thematic slots will choose something different. Players who don't want to bother with complicated rules will leave it aside.

Nevertheless, this is a high-quality video slot, which is worth the attention of Casinoz readers. We hope you will appreciate its features.


  • Different kinds of prize features;
  • Generous free spins;
  • Frequent bonus rounds.


  • Boring theme;
  • Inconvenient paytable;
  • Too complicated bonus terms.

The volatility and RTP of All Star Knockout are average.
