LooneyPop

LooneyPop by AvatarUX is a 5-reel video slot that blends the PopWins™ mechanic with a new ZapReel™ feature. The game begins each spin with 3 rows, expanding in height up to 6 rows during the base game through PopWins™, and further expanding to up to 9 rows in the free spins round. When symbols form a winning combination, they “pop” off the reels and are replaced by two new symbols, which increases reel height and unlocks more ways to win. The ZapReel™, positioned above the main grid, shows three special modifiers every spin which can include multipliers, split symbols, expanding winning symbols, or synced reels; these rewards apply to reels below and become more powerful in free spins. Free Spins are triggered once all five reels reach 6 symbols high during base play; at that point players receive 6 free spins and are offered a Gamble Wheel to try and boost the number of free spins, potentially up to 18. During Free Spins, reels start at 6 high, can grow to 9 high, and reels once fully expanded may remain locked. The game also offers a Bonus Buy option in supported jurisdictions, allowing direct access to the free spins round with presets like synced reels or guaranteed rewards. The theme is cartoony and mad-scientist inspired, filled with colourful characters and science lab motifs, giving LooneyPop a lively and chaotic atmosphere. The maximum potential win is very large when combinations of ZapReel rewards align in the bonus mode.
