Yoh, how did I even lost here? Can someone explain to me what happened??

Unfortunately, scratchcards only let you scratch off 6 out of the 9 spots available. I'm not sure why they do this, but it just makes it harder to win. You have to get a 3 of a kind, so getting half of the 6 to match is much harder than out of 9.

It is unfair to put all 9 up there and limit you, though, so I get the feeling.

You lost because you didn't get three of a kind.  One more snowball and you would have won a snowball.

Yeah its bit annoying when you consider how real scratchcards work why would you ever leave a card unfinished...unfortunately thats just how it is on here if its ever been explained well I'm not in the know

Oooh yeah, now I see why I lost. Its still bubu tho.
