How rolls and luck work together

Summary

In short Raising your luck stat is the most reliable way to pull rarer, stronger units from rolls.

Every roll hands you a random anime unit, and rarity decides how much that unit contributes in battle. Because the outcome is always random, luck is the lever you can actually control. Higher luck shifts the odds toward rarer results. Free codes give you more roll attempts.

Roll result　determined randomly every time you roll
Luck stat　raises your chance of landing a rarer unit
Free codes　add extra rolls without spending anything
Upgrade option　units you already own can be upgraded to hit harder in battle

Placing and upgrading your units

Tips

In short Cover every part of the enemy path and upgrade before waves escalate.

Where you place a unit matters as much as which unit you have. Enemies follow a set route, so units sitting off that route deal no damage. Waves grow stronger as they progress. Anchor your formation around your rarest units and use lower-rarity ones to fill coverage gaps.

Tips worth knowing

Spread units so every section of the enemy route is covered — gaps in coverage let enemies through.
Upgrade before each new wave rather than after you start losing ground.
Use weaker units as support around your core lineup.

What to check when a wave beats you

Check

In short Upgrade gaps and unclaimed code rewards are the two most common reasons a wave feels impossible.

Before you retry a wave you keep losing, run through this list.

Upgrades are maxed confirm every unit in your lineup has been upgraded as far as your resources allow.
Luck has been raised a low luck stat means your roster fills up with weak units and you run short on firepower.
All codes have been redeemed check that no unused codes are sitting in the menu; unredeemed rewards are free rolls left on the table.
Unit positions cover the full route make sure no section of the enemy path has zero coverage.

Redeeming codes without errors

Step

In short Copy-pasting codes instead of typing them by hand is the single best way to avoid failed redemptions.

Codes unlock crystals, potions, free boxes, and other rewards. They expire over time and each one can only be used once per account. New codes arrive alongside game updates and events. As of September 10, 2026, this site tracks 18 working codes for this game.

Open the menu tap the code button on the right side of the screen after launching the game.
Paste the code use copy-paste into the input field rather than typing it manually.
Hit redeem press the redeem button and look for a reward confirmation on screen.
Try a private server if a valid code does not register, rejoin through a private server and attempt the redemption again.
Join the official group the group posts rewards and code announcements.

Why didn't my code work?
