      How to Verify These Results
    

    

      

        This demo uses a provably‑fair random number system.
        Every result shown above can be independently reproduced and verified.
      


      
Base Game Spins

      
    
        
  1. Take the server seed (revealed after play).
    2. 
        
  2. Combine it with the client seed and the nonce.
    3. 
        
  3. Build the following string:
    4. 
        
    server_seed : client_seed : nonce
    
        
  4. Hash the string using SHA‑256.
    5. 
        
  5. The hash deterministically produces the exact grid shown.
    6. 
      


      
Free Spins (Bonus Game)

      
    
        
  1. Use the same server seed and client seed.
    2. 
        
  2. Use the trigger nonce (the spin that started the bonus).
    3. 
        
  3. Append the bonus spin index.
    4. 
        
  4. Build the following string:
    5. 
        
    server_seed : client_seed : FS : trigger_nonce : step_index
    
        
  5. Hash with SHA‑256 for each free spin.
    6. 
      


      

        Because the server seed is fixed before play and revealed later,
        outcomes cannot be modified after results are known.
