The leaderboard only accepts single-player Endless results on campaign maps M1–M4 (the M0 tutorial and co-op maps do not count). After clearing a campaign map, continue into Endless; the Game submits automatically every 10 waves and when the run ends. Without a connection, results are kept on your phone and sent once you are online.

There are two boards. Ranked requires that no tower went above level 7, no generator above level 4, and no Crystals were exchanged for Power during the run; other valid runs go to Open. The “Ranked / Open” switch at the top right of the battle screen starts locked to Ranked so you don’t lose eligibility by accident.

New results are marked “pending” while we verify them by replaying the run; season rewards only go to verified results.

Season S1 ranks the Ranked Overall board and closes at 24:00 on 2026-12-31 (UTC+8). After verification, rewards (titles, Crystals, Ascension Cores) are delivered to your in-game mailbox. See “Season Info” on the leaderboard screen for placements and rewards.

We try to keep old saves playable. If a save truly cannot continue after a rules change, the save screen shows “Cannot continue after the update · N Crystals refundable”: tap “Refund and delete” to get back the Crystals you exchanged for Power in that run (once per run), then start a new one.

Account-wide content such as your Crystal balance, heroes and ascensions is not affected.

For now, progress is stored on your device and scores are tied to it. A transfer code feature is in development: once released, you will generate a code on your old device and enter it on the new one to restore your save and leaderboard identity.

Until then, please keep the Game installed on your old device. Using the same Apple / Google account, tap “Restore purchases” on the Tower Ascension page of the new device to recover Tower Ascension (non-consumable) purchases.

1. Check your connection and fully close and reopen the Game — unfinished transactions are delivered at launch.
2. For Tower Ascension, open the “Tower Ascension” page from the main menu and tap “Restore purchases” at the top right.
3. Monthly Pass daily supplies arrive in your mailbox and must be claimed.
4. Still missing? Email [email protected] with your player information, the product, the purchase time and the order ID from your Apple / Google receipt. We will check and fix it.

Refunds are handled by the App Store / Google Play; request them from your purchase history on the relevant platform (Apple: reportaproblem.apple.com; Google Play: “Payments & subscriptions” → “Budget & history” in the Play Store).

In-app purchases during TestFlight testing are Apple test transactions and are not charged.

During the beta, co-op is a test feature. If players see different things (for example the same tower in different places, or different enemy HP), the games have diverged — a “desync”. The server records when desyncs happen and we are tracking down the causes; co-op stays open in the meantime and does not count toward the leaderboard.

If it happens, sending us the room code and time helps a lot.

Settings → turn off “Send anonymous usage data”; crash reports stop as well. See the Privacy Policy for details.

Email [email protected] with the subject “Privacy request” and the player information shown on the leaderboard screen. Your scores will be removed from the boards, and undelivered season rewards can no longer be sent.

Nicknames must be 2–12 characters using letters, digits and _ - · only. They cannot contain insults or hate, impersonate staff (for example containing “GM” or “admin”), or start with PILOT-. Your first nickname is free; after that you can change it once per season.
