For 243 ways to win a video slot machine, the minimum bet for this Dark Vortex game is only 0.10 per spin, up to a maximum of 50 spins. That's because you need to trigger the eddy current and increase the size of the reel from 3 rows to 5 rows to get power. Then, you need to collect symbols in these mini vortexes to have a half chance to get any decent payouts from the bonus game.

Opening all 5 Vortex reels before exhausting Vortex spins will trigger free spins. Each blue ball you collect will get a free spin, and the pile of wilderness added to the three reels in the middle will be set by the number of pink balls you collect.

Purchase bonus feature: You can bet 80 times to trigger a free spin. Then, you will trigger any operation in 5 to 20 free spins and start from a stacked state of 2 to 10 symbols high. If you bet more than 1 Euro or equivalent currency, this bet is not available.
