Cluster pays groups matching symbols into connected clusters instead of fixed paylines. Check the minimum cluster size, whether diagonal connections count and how a winning cluster is removed. A tumble is a replacement of symbols within the same paid sequence; use the game rules to distinguish it from a new paid spin.
