All Star Knockout slot: features and gameplay
All Star Knockout gives traditional slots a fresh spin with a 5-reel layout instead of 3 reels. Collect stars as you spin to fill the award board and unlock the knockout bonus game. Potential wins of over half a million Euros or Dollars are described, but are not guaranteed.
Theme and Story Line
Fruit icons and 7s give the slot a retro look, while a star-filled award board adds a collection mechanic. Landing star symbols fills spaces tied to the game’s eight symbols. Complete a card to activate the All Star Knockout Bonus, the main feature beyond regular spins.
Graphics, sound and animation
All Star Knockout uses a 16:9 display and was released 11 March 2020. It supports mobile and desktop browsers, including Chrome, Firefox, IE and Safari, for instant play, while some online casinos may offer a downloadable app. Simple 3D artwork recreates a traditional slot with fruit, 7s and bar symbols.
Yggdrasil pairs symbols associated with classic slots with a contemporary presentation. Animated details, an upbeat modern soundtrack and distinctive sound effects give the game a current feel.
Top Casinos to Play All Star Knockout:
Gameplay
Yggdrasil advertises a maximum win of €675,450. The layout has 5x4 reels, displaying 20 symbols at a time, and 20 paylines. Wins run from left to right in sequences of 3, 4 or 5 symbols across reels 1-2-3, 1-2-3-4 or 1-2-3-4-5, respectively.
The game has 8 symbols across 20 paylines. ‘KO’ tops the award table: a 5-symbol win pays 100x, a 4-symbol win 60x, and a 3-symbol win 30x the ‘bet per line’. Other icons include the red 7, white 7 and blue 7, along with 4 fruit symbols: cherry, orange, plum and lemon. Symbols appear in stacks of 1, 2 or 3.
Calculate the ‘bet per line’ by dividing the ‘total spin bet’ across the 20 fixed paylines. For example, a total wager of 40.00 per spin equals 2.00 per line (40 bet total ÷ 20 pay lines). Since the ‘KO’ 5-symbol combination pays 100x the ‘bet per line’, a 2.00 line wager returns 100 x 2.00, or 200.00.
For the full payout list, open the slot’s mobile menu and select ‘i’. The paytable displays each symbol’s awards. Change your wager while viewing it and the listed combination payouts update to match.
Controls also include a ‘Speaker’ button to mute the sound and an ‘Auto spins’ feature. Set the ‘total stake’ for each spin, then select between 10 and 1,000 automatic plays.
Bonuses and Free Spins
Award Board: Each of the 8 symbols has 5 spaces on the board. When a star lands on the reels, it randomly fills one space for a symbol. Progress is saved separately for each stake: changing the wager resets that stake’s board, and returning to a previous stake restores its saved stars.
All Star Knockout: Filling all 5 spaces on any award card triggers the All Star Knockout bonus. The round awards 5 free spins. During the free spins bonus, completing more cards can award additional free spins.
Free Spins Multipliers: At the start of the bonus, one multiplier—x5, x4, x3 or x2—is selected and applies to every win.
Random Bonus: A re-spin may start at random during play. The feature is described as guaranteeing a win on the first spin, followed by further re-spins until no additional win lands.
Bet Sizes, RTP and Variance
The ‘STAKE’ setting offers wagers from 0.20 to 150.00 per spin, covering smaller bets as well as 150.00 spins for high rollers. Yggdrasil gives All Star Knockout a volatility rating of 71.5%; the game is described as medium-to-high variance. Its 96.1% RTP is characterised as average for a Yggdrasil slot.
Conclusion
Yggdrasil Gaming’s All Star Knockout brings the familiar fruit-and-7s style into a modern slot format. The award card is central to its bonus play, but completing it does not guarantee a profit. Payouts appeared more generous in the bonus than in base play, though that observation is no promise of future results.
