BEGINNER GUIDE
New to Anime Duels? Do these in order - each step links to the page that explains it.
1. ROLL CARDS
Press ROLL (or turn on AUTO ROLL). Every 10 rolls, the next roll gets +3 Luck. Rarer cards are stronger.
2. BUILD YOUR DECK
Your Deck holds 4 cards - they fight for you. Open the Deck and press EQUIP BEST, then swap cards as you find better ones.
3. BEAT STORY MODE
Talk to the story NPCs on each map. Beating a stage NPC on Easy makes its card rollable from packs for good.
4. UNLOCK MORE CARD PACKS
Packs unlock as your total rolls grow. Equip one to add its cards to every roll.
5. ROLL TRAITS
Every card can hold one trait. Damage / HP traits help in battle; Luck and Roll Speed traits help your rolls while the card is in your Deck.
6. CLIMB THE TOWERS
Towers give card rolls, potions and items every floor - the further you climb, the better.
7. USE YOUR ITEMS
Potions, instant roll packs and rerolls go to your Backpack. Every item has a HOW TO GET page here.
8. DO YOUR QUESTS + CLAIM THE INDEX
Quests and the Card Index pay potions and rerolls just for playing. Check them often.
