Tutoro runs the tutorial quest, added during Easter 2021. Open it from the badges category, the help screen, or the prompt when you join. You place Wizard, see the range bubble, and upgrade him. Clearing it awards the Tutorial Done badge, 50 coins, and the Tutoro sticker.
How long is a standard match?
On a standard map, Easy ends on wave 25, Medium on wave 35, and Hard on wave 40. The final wave is the boss wave.
What is the difference between mana and coins?
Mana is spent inside a match to place and upgrade heroes. Coins are the lobby shop currency used to buy heroes. Codes that pay coins do not fill your mana bar.
