What is Crossover 21?

So here's the deal with Crossover 21. You're working with cards and trying to match them in a way that adds up to 21. It’s a bit of strategy and a bit of hoping the right card turns up. You don't need to be a math whiz, just someone who likes a good puzzle.

What makes it interesting is how you decide which cards to keep and which to swap out. It's all about weighing your options and sometimes just trusting your gut. Perfect for when you want something engaging but not too intense.
