As a rule the provably fair operators provide the players with the needed tools that are available directly in the game interface. All you need is to enter the required information in the fields to verify the game payout and outcomes. However, it’s not the only way. As it was stated above in the article, today there are third and independent websites and services where you can use the data provided by the casino like server seed, client seed and nonce for double-checking. Besides, there are sha256 hash calculators, using which you can even verify if the server seed has been hashed correctly to make sure that no cheats take place. I recommend you to use both approaches and compare the results at the end of the gameplay. Also, you can pick any out of the bitcoin casinos recommended in the post that are checked by me and my team.
