There are different forms of Elam, but the idea is that there is no particular time when regulation ends. Instead, there will be a target score and the first team to get to it wins. The current proposal is to play the first three quarters like normal and then make the winning score be 24 more than what the leading team currently has.

Most pickup games are Elam style: play to 11 or 21, etc. The benefits are that tedious end of game fouling is disincentivized and by definition every game ends on a game winning shot.
