Beginner's Tips

Select enemies :
You can target an enemy by tapping on them. This will aim not only special attacks, but also passive skills at the targeted enemy.

Free gems from new heroes:
When you summon a new hero, go to the hero's profile and click on the book. Many of them will award you with gems the first time.

Daily free gold:
The "Market" and "Wishing Crystal" tabs have a daily free offer for 5000 gold. Some are hidden in sub-menus, follow the red dot!

Common mistakes to avoid:
Do not strictly adhere to using one hero of each color, as this is unnecessary and will needlessly limit your team composition options. Do not invest any resources in leveling any 2 star heroes, as they have no value beyond the very early game.
