Can´t unlock new decks

[summer lava]

I win with the first few decks and unlock new ones but i have reached the black one and when i win i dont unlock nothing new. Also my colection doesn´t update after that. I play on Mac. I have already restart the game, my mac, unistall and install, delete the profile and nothing works.

Um, after the checkered deck you unlock them from stakes, not beating white stakes with decks

It should say what you need to do to unlock them
