Swoll by Shady Lady is a chaotic tribute to gym culture gone off the rails. Set in a neon-lit garage gym filled with thirst traps and questionable life choices, this 5x4 slot delivers 1024 ways to win, stacked symbols, and a 20,000x max payout. With features like Nudge, Slide, and the explosive Roid Rage, Swoll turns every spin into a freakshow of gains and grotesque transformations.
The Free Spins and Super Free Spins rounds crank up the intensity, with guaranteed stacking and merging for massive win potential.
Swoll has a layout that consists of 5 reels and up to 1024 paylines / ways. The game has several features including Bonus Bet, Buy Feature, Extra Spins, Multiplier Wilds, Nudges, Stacked Symbols, Super Free Spins, and more. Swoll also has a free spins bonus round and this is usually where you can win the big money.
The standard RTP (Return to Player) for Swoll slot is 96.21% (Could be lower on some sites). This payback is good and considered to be about average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €96.21. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 20000x your total bet which is very high and gives you the chance to win really big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
Swoll is a volatile slot, and Shady Lady rates the volatility High (4/5). Volatility, in the context of slot games, refers to how often and how much a slot game pays out. Swoll is designed to appeal to those who enjoy the adrenaline rush of substantial winnings that low volatility slots can't deliver, and are willing to accept the inherent risks of less frequent payouts.
Swoll is a slot that dares to be different—and it succeeds in being both hilarious and horrifying. The merging Swoll symbols and Roid Rage feature create thrilling win potential, especially when the reels align just right. The Super Free Spins round is a grotesque spectacle of body horror and stacked rewards, perfect for players who crave intensity. However, the extremely high volatility, low hit frequency, and graphic theme may alienate casual players or those seeking a more traditional slot experience. If you’re into outrageous visuals and unpredictable mechanics, Swoll is a beast worth taming.
