After 2 years playing this game I still love it, best puzzle game I have ever played. The game will have it's update every half of a month, that means at least 4 new 6 stars characters every month. But the chance to get one of them is kinda low, so I will give you an advice, saving up at least 900 crystals before rolling for any of them. If you are a beginner, there will be a lot of ways to get crystal, so use them carefully and save up for the future uses. Battle bosses and raids are really important, they will give you crystals (First time only) and free characters. Some collab characters will have voiceline when using skill, so it's really worth to have them. And the last, remember to login everyday, do daily quest, there will be some great rewards.
Best site for tier-list, events, gift codes and information for this game is Altema.
