All Star Knockout™

All Star Knockout™ is an online video slot from Northern Lights Gaming with five reels and 20 paylines. The game uses a “Win Spins” base mechanic, where play continues until the feature ends, while golden stars build progress toward bonus rounds. The return to player is 96.09%, with stakes from £0.20 to £100 and a maximum win of 4,500 times the stake, capped at £250,000.

The main bonus trigger comes from collecting stars on a single symbol. When five stars land, the free-spins round starts, and the award card tracks the collection process. During free spins, symbols can be knocked out, which can retrigger more free spins and raise the multiplier, creating a sequence of bonus rounds linked to the star feature.

This review page is available with a demo version, so players can play for free and practice before playing for real money. The slot uses a retro space theme with star-focused visuals and a portrait mobile layout.
