How to play

Crown and Anchor is an 18th Century British Royal Navy gambling game. Login via Nostr and get 20 bets to start.

The rules are very simple:

Bet on one or more symbols, by clicking on them. When you are done, click PLAY.

Three dice are then thrown…

You win evens (1:1 + stake) on any single symbol matched. (eg: 👑❤️♦️)

You win doubles (2:1 + stake) on any symbol that appears twice (eg: ❤️❤️♦️)

You win trebles (3:1 + stake) on any symbol that appears three times (eg: ❤️❤️❤️)

This game is a provably fair game of luck. However, like all gambling games, the house has a mathematical edge (7.87%), so you will eventually lose more than you win. You can read more about the game math here.

To comply with gambling laws, it is therefore provided purely for education and entertainment only, there are no payouts or moneys worth prizes. Credits cannot be redeemed, transferred or spent on anything other than gameplay. Have fun!
