Lines All Star Knockout™ Ultra Gamble is a 5-reel, 20-line video slot by Northern Lights Gaming with an RTP of 96.09% and a maximum win of 4,500x bet, capped at £250,000. The game uses a retro knockout theme built around stars, with a default total stake of £1 and betting options from 20p to £100. A free demo version is available for players who want to play for free and practice before playing for real money.
The base game includes Win Spins, where spins continue while symbols are knocked out and collected stars may lead to additional free spins. Golden stars are tracked on an award card, and five stars on one symbol can activate a freespin round. The game also includes a multiplier bonus in freespins, adding another layer to the slot mechanics.
One of the main features is Ultra Gamble, which offers a chance to win more stars, remove more symbols and unlock higher payouts or more free-spin rounds. Visual elements shown in the game include the paytable, bonus screens, multipliers and big win displays, giving a clear view of the slot's features before play begins.
