The more bonus rounds an online slot machine has the better. For example, the slot must offer free spins with win multipliers. It helps even more if the slot has a Cascading engine. During a winning combination, the symbols explode. New symbols fill the gaps they leave, essentially offering you chains of wins. Furthermore, many slots include wilds, sticky wilds, walking wilds, pick me games, respins, and wild reels. Another thing players overlook is the RTP and hit rates. The best RTP for slots is above 96% while the hit rate must be 25% plus. Be on the lookout for Megaways slots, Infinity Reels, and Role-Playing slots for a highly interactive playing experience.
