Well, I have to share my experience again, because this nonsense couldn't be more obvious. Avoid online casinos, especially when there's vacation pay or Christmas bonuses.

They immediately shut down the slots, there are hardly any winning payouts, free spins are much rarer and, above all, the free spins are bad.

You basically have a subscription to it from the casinos.

Above all, avoid the Big Bass and Bigger Bass series—you can also safely ignore the book games from Playngo.

Interesting view. 

Could you tell us in which casinos you have experienced this? 

As for withdrawals on holidays and such, I think everyone has to take it into account that it usually prolongs withdrawals, because banks are often closed. Some casino departments may not work either. There are various vacations during holidays and so on and so sometimes casinos can be overhelmed in terms of withdrawals. 

But it certainly shouldn't take a few weeks for players to get their money and it should always be at a proper, reasonable time. ??
