When spinning through the haunted world of Dark Vortex, players should understand the betting flexibility, RTP percentage, and volatility at play. Here's a closer look:

Bet Sizes

Dark Vortex accommodates low and high rollers with bet sizes ranging from $0.20 to $100 per spin. This range lets players find the wager amount that matches their bankroll and preferences.

As a highly volatile slot, Dark Vortex is prone to extreme swings between big wins and long dry spells. Players will need to exhibit patience and solid bankroll management to ride out colder streaks.

What is the maximum payout possible?

The maximum win available in Dark Vortex is a whopping 350,000 coins! This massive jackpot can only be won during the Vortex Free Spins bonus round. With some luck, the expanding wilds can cover entire reels to create huge wins of up to 350,000 coins or more.
