2. Account & new iPhone

Playing on one phone

You play with a device account created on this iPhone. Progress that lives on the server (heroes, inventory, display name, synced campaign) is tied to that account while you are online.

Keep progress on a new iPhone (or after reinstall)

  1. On your first iPhone: open Player Setup → tap Link Sign in with Apple once (same Apple ID you will use later).
  2. On the new iPhone (or after reinstall): open Player Setup → tap Sign in with Apple (same Apple ID) before you play much.
  3. You should see the same display name / account after sign-in.
Moves with Sign in with Apple Usually stays on each phone
PlayFab account / PlayFab ID Language, sound, battle VFX
Heroes, inventory, currency Tutorial “already seen” flag (may show again)
Display name
Campaign stars / unlocks (after cloud sync)
Ranking / uploaded defenses / party membership

Tip: Link Apple on the old phone first, then Sign in on the new one. Same Apple ID on several iPhones shares one game account.

3. Heroes & inventory

4. Campaign

  1. Open Campaign Map and pick a chapter / stage you have unlocked.
  2. Clear stages to unlock the next ones (usually need at least 1★ on the previous stage).
  3. Earn up to 3★ per stage; higher stars record your best clear.
  4. First clears may grant XP to the heroes you used and/or a pick-one reward.
  5. Campaign progress is saved to your account while you are online (after login / Apple link it can follow you to a new device).

If a stage looks locked: clear the previous stage first, or Sign in with Apple if you are on a new phone and expected old progress.

5. Teams & lineups

6. Combat modes

Campaign (PvE)

Story and adventure stages against computer opponents. Best for learning heroes and earning early rewards.

Your Team / PvP (other players)

Upload or refresh a defense roster, then attack another player’s defense. Daily attempt limits may apply.

Rank Match

Join the ladder for the season, set defense teams (1–6 team formats depending on mode), fight ranked opponents, and submit results as the UI prompts. Seasons and rewards follow the in-game schedule.

Let’s Vs (party / clash modes)

Includes modes such as Team Clash, Hero Clash, and Accumulate Fight:

  1. Create or join as directed on the Let’s Vs hub.
  2. Set lineups / ready when asked.
  3. Fight or resolve before the deadline shown in the UI.
  4. Rewards are often delivered by Mail.

Read the on-screen status text for timers, cooldowns, and whose turn it is.

7. Stores & gold rewards

Store Typical use
Hero Store Heroes / related packs with in-game currency
Magic Store Magic / upgrade materials
Gold Reward Watch an optional rewarded video ad to earn in-game gold

Gold Reward (optional ads)
