Warning: Codes change without notice. If a code returns 'Invalid', the set has rolled over — check back the next day for a fresh list.

Spend Credits on Crates the Smart Way

  1. Always redeem codes first to maximize your bankroll.
  2. Set a hard stop-loss (e.g. spend no more than 30% of credits in one crate session).
  3. Don't single-pull — most crates discount 5+ pulls.
  4. After pulling, immediately switch to ranked and test the new knife before pulling again.
  5. Save credits for limited-time crates that offer higher Cosmic odds.

Crates that advertise 'guaranteed Rare or higher' are the safest pull points for free-to-play players. Common-only crates usually have negative expected value.

Frequently Asked Questions

Do codes expire?

Yes. If a code shows 'Invalid' in the redeem menu, it has expired. New codes drop with each update and during limited events.

How often should I open crates?

After reaching your stop-loss or unlocking a Legendary, switch to ranked. Crate ROI gets worse the more you pull in a single session.
