Not on one spin but it's not uncommon for casinos to market wins that are cumulative. I think it was highlighted in a thread here recently in fact.
And even if he did, with Luxury Casino's $4k max cashout per week, he won't receive the full amount for 5 years anyway.
Personally I think Microgaming should put a maximum bet cap on games at casinos where a win can exceed the maximum cashout amount.
"3.Players who win a sum that is 5 times or more greater than their total purchases across all Casino Rewards partner casinos will only be able to withdraw their winnings at a sum of $4000 a week. All progressive wins/payouts are exempt from this clause."
That term is on all CR casinos.
