You can play the game to completion without spending a penny. Differences with the paid version are:
- 2 classes unlocked by default (Warrior, Mage) instead of 3 (Warrior, Mage, Rogue).
- Occasional ad between fights vs No ads.
- 20% of the regular legacy gold on death.
Ads and legacy gold restrictions are disabled automatically once there’s 3 optional classes/skin packs unlocked or more.
There’s also runes and scrolls available for purchase which are not offered on the paid version but since the game balance is the same they are not required to enjoy the game.
