Question about PLO

Quick question about PLO. I just started playing it so I dont know all the rules and one thing caught my eye. I was playing Heads-Up in Spin&Go PLO with some guy. My hand was 4 and 9 of Hearts and 2 random cards. His cards were Q Hearts and 10, 8 and A Spade, Club and Diamond.
Community cards were 3 of clubs and A, K, J and 10 Hearts. I had Flush, but he had Royal Flush and I still won. How is that possible?

you can only two of your 4 cards given even so if 3 of his cards create a royal flush when combined with the board at best he can only have a queen high flush, not the royal.

or maybe you just miss read his hand when shown.

possible it's lol

You can't make a flush in PLO with a rainbow hand (one of each suit).

Two cards MUST play out of your hand and three cards on the board MUST play at all times.

You won with a 9 high flush because you had 2 hearts in your hand, he does not have a flush with only one heart and 4 other hearts on board (since only 3 board cards can ever play, he has a straight with the board and cards you described).

PLO is not like hold'em where you can use the 4 or all 5 board cards if needed, you specifically only use 3 board cards and two cards from your hand.

Good luck to you!

Ok, thanks guys!
Omaha is pretty interesting, I'll try to improve in it in coming days.

You can only use 2 cards from your hand and 3 cards from the community cards to make the best possible hand.
