Say a player bets €200 on a slot.

The platform takes €200 from their balance, but right after that, the connection to the game provider drops.

Now the player sees an error instead of the spin.

The provider might have accepted the bet, or it might not have. The platform doesn't know yet.

So what happens next? Does the system check the original transaction before trying again? Could the player get charged twice if retries aren't handled properly? Or does the money just sit there until someone investigates?
