What is Ouroboros Solitaire?
Ouroboros Solitaire is one of the leanest, weirdest deckbuilders I've played in a minute. It's a genuine piece of design that's so elegant you can actually play the entire game with a physical 52-card deck and a Joker.
Gameplay
You're diving into a loop centered around 'Circular Arithmetic' (Modulo 13), which is basically a brain-burner where you manage a limited hand to take down enemies that scale infinitely. It's not about slapping cards down; you're circulating resources to hit specific numbers to survive. If you've got the 'just one more turn' itch from Balatro, you'll find it here, though it's more about precise math than gambling. You'll hunt for 'Hand Bonuses'—poker-style combos—to trigger instant kills, while using Bribes and Special Cards to add layers to your strategy. Since you're fighting a 'Threat Deck' in an endless run, the variety comes from seeing how long you can last before the scaling crushes you. Don't expect a massive talent tree for meta-progression; the real reward is just your own skill improving and watching your high score climb. At $3.77, it's a weirdly priced but lean experience that doesn't waste your time with filler.

8/10. Grab this if you want a pure, complex card game that respects your time. If you hate doing mental math while gaming, you should definitely skip it.
