What are some good games that use the cluster pay system? I've been exploring different types of slot mechanics recently, and the idea of winning by landing clusters of symbols rather than traditional paylines really intrigues me. It seems to offer a fresh and dynamic way to play. I've only tried a couple, but I'm looking for more recommendations for games that utilize this feature effectively and provide an entertaining experience. Any suggestions for titles with exciting bonus features or great graphics would be much appreciated.
