Three Ways to Play!
1. Continuing Leagues
We have a community of longstanding members who play in our continuing leagues--the original concept for our game--running season after season, like MLB franchises. These leagues require longer-term player signings, draft pick trading, financial planning and management, and strategies oriented to the long haul of managing a franchise. These leagues are configured in many different ways. Some draft by historical era, some by random players selection, and some by a sequence of years. Some span the entire range of players from 1871 - present. Others focus on a single era, e.g. the dead ball era, or players since the turn of the millennium. Division structures and playoff structures vary.
2. Single Season Leagues
Members can play in leagues that run for only a single-season. These leagues draft the 1st of each month. Schedules play three times daily for maximum control of your team. Each season is approximate 2 months duration. Teams come financially stocked. Owning teams in these leagues free you from financial worry and planning.
3. Custom-Designed Leagues
Members can design and sim their own leagues by building them from the ground up or selecting historical teams, or a combination thereof. The software offers full managerial control of every team in the custom leagues and you can play the season schedule at your own pace.
Version 7 of our software introduced players from the seven Negro Leagues recognized by MLB (1920 - 1948). Our baseball sim combines a competitive universe of statistical precision with a passion for baseball history and lore. Questions about our product can be directed to
