Basketball League Sandbox

Your league. Your rules. Your basketball universe.

Basketball League Sandbox is a basketball simulator for fans who want to shape an entire sports world. Customize your basketball league, simulate seasons, follow rivalries, and watch new dynasties emerge.

Explore Commissioner Mode, experiment in Sandbox Mode, or build a lineup in Unlimited Draft. Whether you enjoy basketball simulation, league management, or uncovering the stories behind the standings, there is always another season to explore.

BUILD YOUR BASKETBALL UNIVERSE
Create a league with real-player rosters, customize its structure, and explore expansion. Real players fill available roster spots first, with fictional players used when expansion exhausts the available pool. Keep multiple saves to explore different basketball worlds.

TAKE CONTROL IN COMMISSIONER MODE
Shape league rules, explore team finances, and guide the future of your competition. Review schedule fairness, follow fans, and see how rule changes affect your league. Make decisions that influence more than a single team.

EXPERIMENT IN SANDBOX MODE
Ask “what if?” and explore the results. Use scenario presets, a trigger builder, and what-if experiments to discover different outcomes. This sports simulator gives you room to explore your own ideas.

SIMULATE SEASONS AND FOLLOW EVERY GAME
Use season simulation to move your league forward, then check the calendar for upcoming games and remaining matchups. Track standings, power rankings, player stats, and team performance as the playoff picture develops.

REVISIT THE ACTION
Explore game replays with shot maps, momentum charts, and adjustable playback speeds. Jump to the fourth quarter or final two minutes to revisit the moments that decided a game.

FOLLOW PLAYERS AND TEAMS
Explore player development, contracts, health, and relationships. Check team chemistry, coaching, rivalries, and finances. Follow favorite teams and players as their stories unfold across seasons.

CONNECT YOUR BASKETBALL WORLD
Go beyond one competition with connected leagues, transfers, loans, promotion and relegation, national teams, and a tournament creator. Build a basketball universe where each season opens new possibilities.

EXPERIENCE THE OFFSEASON
Continue through an 18-step offseason as your league prepares for another year. Follow roster changes, player development, and the decisions that could shape the next contender.

PRESERVE LEAGUE HISTORY
Turn results into a lasting record. Explore championship runs, Finals upsets, draft classes, All-Star history, and franchise achievements. Compare legacies and see which teams become dynasties.

DISCOVER STORIES WORTH FOLLOWING
Stay connected through the timeline, newsroom, and story archive. Track league developments, follow emerging rivalries, and create share cards for memorable moments.

BUILD A LINEUP IN UNLIMITED DRAFT
Take a break from running your universe and explore Unlimited Draft as a separate way to enjoy building a basketball team.

Basketball League Sandbox combines a basketball simulator, a season simulator, and a customizable league sandbox in one game. Create your competition, follow its stories, and discover what happens next.
