I had the "Four fingers" joker that allows you to form flushes and straights with only 4 cards.
When I tried to play a straight from King to 9 with all Diamonds except a 10 of Spade, the game considered it a Straight Flush (see screenshot).
It probably happens because the game detects a Straight Flush as follows:
- Is there a straight?
- Is there a flush?
If both conditions are fulfilled, the hand will become a Straight Flush.
However, in my opinion, it should only be considered a Straight Flush if another condition is fulfilled:
3. Are the cards in the straight and the cards in the flush identical?
In my case it was annoying, because I had Straight upgraded to Level 8 and Straight Flush was still on Level 1, so I had to get rid of the Diamond 9 to get more points.
