What are Skull Up codes used for?
In Skull Up, special codes give you free resources that instantly help you build and strengthen your army. Unlike waiting for resources to accumulate over time, using these codes provides an immediate boost, letting you progress much faster.
You’ll often earn rewards like Diamonds and Gold to help you summon new characters and upgrade existing ones. You’ll also get AFK Souls, which boost your earnings even when you’re not playing, and special items like Wishing Stars or Advanced Soul Cards that make summoning more powerful characters easier. Using these rewards effectively lets you build a stronger team more quickly and avoid getting stuck in long, slow grinds.
