How to play Vault Breaker

Vault Breaker is a one-pick reveal with a bit of drama. Here’s how it works in the demo below.

  1. 1

    Face the vaults

    Each ticket shows a set of vaults. The demo deals three tickets so you can crack a few.

  2. 2

    Pick a vault

    Choose one vault and swing its door open. The vault you pick can’t change the outcome, it was set before you chose.

  3. 3

    See the haul

    The open vault reveals cash, credit or a miss. Every result is decided on our server the moment the round starts.

Vault Breaker questions

Can I win cash on Crack the Vault now?

Not yet, this is a free demo with no real prizes. Instant wins are planned for future competitions, where you’ll crack a vault for real tax-free cash on qualifying entries.

Does it matter which vault I pick?

No. The contents are decided on our server before you choose, so every vault holds the same result for that round. The pick only changes the reveal.

Is Crack the Vault fair?

Yes. Each outcome is set server-side the moment the round starts and can’t be changed from your browser.

Is Crack the Vault gambling?

No. It reveals instant prizes on skill-based competitions that offer a free entry route, so it falls outside UK gambling law. 18+.

VAULT BREAKER

Pick a vault and swing the door open. Whatever it was holding was decided on our server the moment you played, the vault you choose just reveals it.

Fair by design: how it actually works

The outcome is decided on our server the moment you play, not in your browser, the game just reveals it, so it can't be tampered with from devtools. When live, each entry is tied to a real ticket, uses cryptographic randomness, and draws down the real prize pool atomically so a prize can never be won more times than it exists. This is a playable demo; it runs server-side on our live site with a local fallback so it still works offline.
