Zero21 is a deceptively tricky game built around one straightforward rule: keep your total between 0 and 21. Simple? Not quite. This solitaire-style twist on number challenges blends strategic card collection with tension—perfect for unwinding while testing your focus.

Every decision counts, and the closer you get to victory, the sharper the stakes bite.
