Flux is a video slot experience created by the provider Thunderkick. In this Flux slot review you’ll learn about its core features (including RTP, max win, and volatility), the bonus mechanics, and what helps the game stand out — along with the areas where it may fall short.
Flux is played on a 5 reel layout with up to 15 paylines/ways. The game includes a variety of features such as Expanding Reels, Extra Spins, Stacked Symbols, Stacked Wilds, Win Both Ways, and more. There’s also a dedicated free spins bonus round, which is typically where the game’s biggest win potential comes into play.
The standard RTP (Return to Player) for Flux slot is 96.2% (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 €96.2. 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 2562x your total bet which is pretty high and gives you the chance to win quite big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
Flux is a low volatile slot, and Thunderkick rates the volatility to 2/5. Volatility, in the context of slot games, refers to how often and how much a slot game pays out. Flux may not offer the massive winnings that high volatility slots can provide, but it does offer a more reliable and consistent winning experience. This makes Flux a popular choice among players who prefer a game with lower risk.
