This isn't fantasy basketball.
“I already play fantasy.”
Fantasy is a passenger seat. You pick real players off a list and hope they score. Here, you're the GM. You scout prospects through fog -- every front office sees different intel. You negotiate with an AI agent who has a name, a personality, and zero interest in giving you a discount. You manage a locker room where chemistry actually matters and a disgruntled veteran can tank your season. This is the driver's seat.
“I play single-player sims.”
So do we. Solo mode gives you the full engine -- same scouting fog, same agent negotiations, same depth -- at your own pace. $1 for your first season. Sim a decade in a weekend or take your time. But when you're ready for a draft night with real people panicking, a trade deadline with real rivals, and a forum where someone just posted “Why I'm winning this league and you're not” -- multiplayer is right there on the same platform.
“I could build my own.”
We did. It took 25 years.
Everything a league needs.
No spreadsheets required.
Simulation engine, community tools, and league hosting all in one place. Multiplayer-first and fully hosted.
The Simulation
Scout through fog that’s unique to your front office. Negotiate with AI agents who have names, tendencies, and grudges. Manage a locker room where chemistry actually matters. 500+ real plays, 100+ ratings per player, and 25 years of competitive multiplayer tuning behind every sim.
Live Draft Night
Real-time snake or lottery drafts with your whole league online. Built-in war room. Scouting reports. Trade-up negotiations happening in chat. The kind of night you block off on your calendar.
Forums & Chat
Every league gets its own forum and real-time chat. Trash talk. Trade proposals. Power rankings. Podcast uploads. No Discord required -- and if you already have one, link it right in. Nothing to host, nothing to set up.
Commissioner Tools
Manage rosters, resolve disputes, set league rules, control sim speed. You're the commissioner -- we give you the controls without the headaches. No servers. No spreadsheets.

Someone leaves your league? Fill the spot from the Lobby in minutes. Active managers are always browsing for their next league. Open teams get visibility across the entire platform automatically.

Every league runs at its own pace
Some sim daily. Some weekly. Some blast through a season in a month. The commissioner sets the speed. You play accordingly.

Looking for a DDS alternative?
Draft Day Sports, Fast Break Basketball, and Basketball GM are all great solo sims. But if you want hosted multiplayer, built-in community, and any-device access, you need something different.
Play anywhere
Check your roster at lunch. Set lineups on the couch. No desktop required.
Automated sims
Your commissioner sets the schedule. Games sim automatically. No coordinating “free time” with 30 people.
Always current
New features ship constantly. No patches to download. No “Version 2026” to rebuy.
Zero setup
No installs, no file syncing, no “who has the latest save?” Open your browser and play.
“But is the sim actually good?”

The single deepest, most realistic basketball sim I've played in 20 years. Truly the FM of basketball.

It's hard to say just how good it is. It's so deep it's ridiculous. The community makes it perfect though.

Multi-League GM

The pro league is way more in depth than college... which is hard to even comprehend because the college sim is the greatest sim experience I've ever played!
