Vault Breaker questions
Can I win cash on Crack the Vault now?
Not yet — Grand Draws is pre-launch, so this is a free demo with no real prizes. When we open 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 provably fair?
Yes. Each outcome is set server-side the moment the round starts and can’t be changed from your browser, so the game is provably fair.
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+.

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.
Provably fair, 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.
