What is a Bitcoin Slot?
A Bitcoin slot is an online slot game that can be played with Bitcoin and other cryptocurrencies.
In today's world, Bitcoin slots aren't different from classic online slots. Slot developers ensure that their games are compatible with traditional online casinos as well as crypto casinos, which means that you'll be able to find these games in every corner of the internet.
Bitcoin slots, and Bitcoin games in general, have three main bases:
- RNG systems that ensure each result is random and unpredictable.
- Smart contracts that act as assurances that money will be paid out.
- Provably fair elements that lets players track the results to ensure fairness.
Provably Fair Games: A Key Part of Online Bitcoin Gambling
Provably fair games are online casino games that let you check and confirm that every result is truly random and not manipulated. They use cryptographic technology to generate and verify outcomes, so both the player and the casino can prove the result is fair. This means you can see how the result was created and confirm that neither side changed it after the bet was made.
