Welcome to Sleeper!
Fantasy basketball can feel like a lot. The NBA season has 82 games, and in traditional fantasy basketball leagues you must set your lineup every day. This can get tiring, and many players lose interest mid-season.
Sleeperâs Lock-In Fantasy Basketball makes the game easier and more fun.
Instead of daily lineup changes, you make weekly choices.
Hereâs how it works:
When your player finishes a game, you can lock in that performance.
If you lock it in, that score counts toward your fantasy points for the week.
But you must lock it in before that playerâs next game starts.

This format keeps things fair. Without it, managers who lineup players with more games in a week could win the match up, just because their players had extra chances to rack up points.
Sleeperâs Lock-In Fantasy Basketball is simple, fair, and more strategic. You only need to focus on the best game each week from each player.
