I want to share my controversial story with you.
When I had a very weak laptop (old), and I went to an online casino to make one of the biggest bets of my gambling session, suddenly the image in my browser froze and the animations did not play.
And I clicked on the SPIN con a few more times. After which everything update on my screen. And I saw that I had spent some money, but it did not bring any result. Did the system work correctly at that time?
I have almost identical experience where I set a bet but it does not instantly have the result due to an internet problem, to explain it, I bought a bonus buy in one of the slot provider and after buying it and some spins from the bonus buy, my internet got disconnected. After a minute or two, my connection came back, check my bet history, can't find that bonus buy history but my account was deducted of that bonus buy and did not receive the winnings from that buy. I just shrugged the glitch and after a day or two, I found my account credited with the amount won from that glitched bonus buy.
I do not know if the same thing will hapen to you but I think it is better to just wait and check your bet history from time to time if you can see that glitched spin in your bet history.
I understand that most likely many will say that I am to blame for this situation, but shouldn't an online casino stop accepting bets if it sees that the "gears of the game" are not spinning as they should? After all, this is a game for real money of the gambler.
I think there is a line on the Terms and conditions of many casinos that losses from glitch won't be refunded by the casino. Better check if the platform you played have them, if not then you can probably file a support ticket about what had happened.
