Mystery Box Reveal
BlitzRocket's Mystery Box Reveal tool is a free instant-win playground where players pick one of several boxes to reveal a prize. The winning tier is drawn from your odds before the box opens, so the choice is cosmetic and the math stays fair and auditable.
Prize tiers & odds
Every play lands on exactly one tier. Odds must add up to 100%.
100% allocated
Win chance per play: 60%

Miss outcomes (“Try again”) count toward the 100% but never award a prize, so they don’t need a code or link.

Compliance note
An instant-win game awards prizes by odds you set as each person plays. That is different from a sweepstakes, which picks winners at the end. This playground is for designing and testing mechanics — it is not legal advice. Publish clear rules before running a live promotion.

How does a mystery box reveal work?
You set prize odds, the tool draws a result, and the player picks a box to reveal it. Boxes are a visual mechanic — the outcome comes from your configured odds.
Is the mystery box game free?
Yes. Design tiers, set odds, and open boxes for free. Upgrade to a hosted Blitz Rocket campaign for email capture and fulfillment.
How many boxes can I show?
The playground supports three to six boxes. More boxes increase drama without changing the underlying prize odds.
Is picking a box random?
The prize is drawn from your odds before the reveal. Which box the player taps only controls the animation, not the odds.
