Balatro

Balatro has 8 difficulty levels, starting with white stake which is the default setting. For each deck you can only unlock the next stake by completing the previous one. Red stakes is level 2, so you'll need to defeat the white level to unlock it. It's not terribly hard compared to white stake - the only difference is that the small blind rewards no money. Unless you're scaling a deck (i.e. growing it over time by playing certain hands in conjunction with jokers, using discards etc), the reward for skipping the small blind is usually better than playing it anyways and getting the measly $5 or thereabouts.
