Every result is provable.

Dragon's Den results aren't drawn from a black box. Every provably fair game, in the in-game hall and in our Discord arcade, gets its result from a pair of published seeds with SHA-256, so anyone can recompute any bet, on any machine, and get the same result we did.

Below are the games we run: the In-Game Hall games and the Arcade games in our Discord. Got a bet of your own to check? Use the Verify link on its result, or sign in to see every game you've played.

How verification works

step 1

Place a bet in the hall, or play an arcade game in Discord. The result posts with a Verify link.

step 3

This site recomputes the roll in your browser, and hands you the same Java to run anywhere you like.
