Improving both your monster and your city is vital! They will become stronger and will unlock higher level leagues for greater tournament rewards!
Leveling up your Monster!
You earn experience points (XP) by completing battles. Winning a battle earns you more XP, but every battle earns your monster some XP.
You can also gain XP by feeding excess cards directly to your monster. The more rare the card the more XP it will receive.
You can feed your cards to any unlocked monster in the Monster Screen.
Tap on the Feed button.
Tap, hold and drag any card currently not in a deck to your monster. He will then eat the card and earn XP.
Please note that once a card is fed to a monster it is removed permanently from your deck.
You can select either Monster or City cards by tapping the buttons on the right of the screen.
When you level up your monster it will increase a random stat. Every 10 levels will increase all its stats and total strength, bringing you closer to unlock the higher level leagues!
