Hello,

I stumbled upon a variant of Streetball known as 'Twenty-One' recently. It involves 3 or more players, each with his own score battling to be the first to score 21 points.

That seems pretty exciting to me, but there's one rule of 21 that I don't understand. After scoring one basket, you're required to attempt some free throws, then the ball goes 'live after you miss'.

I'd like to know why that rule exists and whether it's possible to have an enjoyable game without that rule: just dribbling and scoring and clearing.?

Thanks!
