I think I myself faced this in other casinos as well. What happens is that when you start spinning, your casino balance updates in real time, but the slots take time to update your balance. In most cases, it delays because the slots need to complete the animation and display the final win amount, and only then is the update reflected in the slot game. Additionally, slots occasionally display an incorrect balance. It happened to me before. However, I have been unable to access Bitz for a few days now.

As for the second slot, I can see the coin information at the top. This slot counts your balance as coins. For your 8.82 Euro, it is showing 882 coins. Each time you bet and lose 0.2 Euros, you will lose 20 coins from your balance. The same applies when you win.
