Frequently asked questions

How does the mystery card work?
A card sits face down until you tap it, then flips to reveal a random item from the deck. Turn on 'once per round' and each card is drawn only once until you reshuffle, with a counter showing how many are still face down.
Can I create a custom mystery card deck?
Yes — type any prizes, forfeits, tasks or messages, one per line, and they become the deck. Your list is the deck, so the tool works for anything you can write down.
Is there a mystery card generator app?
No app needed — it runs in any browser on your phone, tablet or computer, with nothing to download or install.
How is this different from the playing card picker?
The playing card picker deals real cards from a standard 52-card deck. The mystery card reveals from a deck you write yourself — prizes, dares or messages — so it's built for surprises rather than card games.
Is the result truly random?
Yes. Every outcome uses your browser's cryptographically secure randomness, so it is unbiased and unpredictable — just for fun.
Is it free and private?
Completely free, no sign-up. Everything runs in your browser, so nothing you type is uploaded.
