All Star Knockout Theme/Symbols

All Star Knockout has a fruit machine feel – with an upbeat soundtrack, symbols include low value lemons, plums, oranges and cherries. There are also blue 7, white 7 and red 7 symbols. The most lucrative symbol is the KO (Knockout) symbol which pays 1.5, 3 or 5 times your stake for 3, 4 or 5 across any of the 20 paylines.

Award Board

At the beginning on any game or when the award board is empty, 12 bonus stars will randomly populate the board to help you.

Award symbols or ones that give you extra free spins are removed from the reels for the duration of the free spins. Prior to the free spins commencing, a multiplier of 2x, 3x, 4x or 5x is chosen and applied to all winning combinations.

Random Bonus feature

After a losing spin in the base game, you could randomly trigger the Random Bonus feature – you will then get a number of win spins, up to 3 per bonus. These are free spins which are guaranteed to give you winning combinations. The Random Bonus feature can also trigger the All Star Knockout Bonus feature.

All Star Knockout thoughts

The All Star Knockout slot is simple and reminiscent of old-school fruit machines. Vibrant and fast-paced, it has an RTP of 96.09% which is decent. Variance wise, it’s medium to high with maximum wins of 1,000 x stake per spin. If you add in the potential 5x multiplier in the free spins, you could win 5,000 x stake per free spin – for some reason, Yggdrasil have stated the max win is 4,500 x stake per spin.

Whilst fruit machine slots have their appeal, there’s nothing revolutionary or unique about All Star Knockout – you should try Temple Stacks: Splitz which uses a unique mechanic or Brazil Bomba which is a grid slot (both by Yggdrasil Gaming).
