The strange part wasn't hitting a good streak. It was opening the game the next day and immediately remembering there was still one card missing from a collection. Not a jackpot. Not a leaderboard position. One card.
That's pretty much how the whole thing works. Spins happen in the background while collections slowly fill out, gems pile up, and new unlocks appear when you least expect them. Before long, you're checking progress bars you didn't even care about when you started.
