How to Play

The Rules of 21

01

First to 21 Wins

The goal is simple — reach exactly 21 points before anyone else. No shortcuts, no luck. Pure skill and execution.
02

1 Point — Inside the Arc

Any basket scored from inside the 3-point line counts as 1 point. Standard. Straightforward. Stack them up.
03

2 Points — Behind the Arc

Drain one from deep and you earn 2 points. You must call your shot before attempting — otherwise it counts as 1.
04

Make It, Take It

Score a basket and you keep possession. Your run continues until you miss. No rest, no mercy — keep attacking the hoop.
05

Dribble Out After Rebounds

After any missed shot, the player who grabs the rebound must dribble out past the 3-point line before attacking the basket. No cherry-picking.
06

Score Exactly 21 — No Going Over

If your score exceeds 21, it resets back to 13. Calculate every shot. One careless bucket can cost you the whole game.

Points System

Inside the Arc

Any bucket from inside the 3-point line. The bread and butter of the game.

Behind the Arc

Call your shot before you shoot. Drain it from deep and double your points in one move.

Exact Score to Win

Hit it exactly or bust back to 11. Every shot counts. Don't overshoot your greatness.

Game On.

You know the rules. Now prove you can run the game. Sign up, step on the court, and compete for your city.

Winning Edge

🎯

Count Your Score Constantly

Know exactly where you stand at all times. If you go over 21, your score resets to 11. One accidental bucket can flip the whole game.
📣

Always Call Your 2-Pointer

Step behind the arc without calling it and the bucket only counts as 1. Announce your shot loud and clear before you pull up.
🔒

Defense Wins Games Too

You can block, steal, and contest every shot. No free rides. Shutting someone down when they're on a run can completely change the momentum.
💨

Train Your Conditioning

You play both ends every possession. Fatigue is your enemy. The player who stays sharp in the fourth quarter of a long run usually takes the win.
⚡

Tiebreaker — Sudden Death Arc

If two players reach 21 on the same turn, it goes to a sudden-death shootout from behind the arc. Make yours. Don't choke.
