I tried this slot when I came across https://indian.1xbet.com/en/slots/game/77622/vortex it does not have standard reels but more like a 5x5 grid or something similar. Wins happen through clusters, meaning groups of matching symbols, which makes it pretty dynamic. Bonuses trigger fairly often, but there can be long dry spells too. If you like something unusual without standard paylines, you should give it a shot.
