Overview

Dynasty League Baseball is a detailed baseball simulation board game using three dice (red, white, blue) and individual player cards for hitters and pitchers. The game recreates real baseball with comprehensive ratings for batting, fielding, pitching endurance, and more. It is played according to official baseball rules, with dice rolls cross-referenced against player cards and various charts to determine outcomes. The game supports both individual replay and full league play with drafting, contracts, and seasons.

Components

Setup

  1. Each manager writes their lineup on a scoresheet, selecting a starting pitcher and batting order.
  2. Weather: Home team manager rolls white and blue dice (generating 0-99) and consults the Weather chart for the region, month, and day/night status to determine temperature, sky, precipitation, and wind.
  3. Umpire Crews: Assign a crew to each series; roll two dice to determine the home plate umpire.
  4. Determine batting order and starting positions per normal baseball rules.

Turn Structure

The game follows standard baseball innings. Each half-inning:

  1. Roll dice (red, white, blue) to generate a 3-digit number (000-999).
  2. Check the appropriate card:
    • Numbers 0-499: Check the hitter’s card
    • Numbers 500-999: Check the pitcher’s card
  3. Find the result in the correct column (vs. Right or vs. Left, depending on pitcher/batter matchup).
  4. Resolve the play: Results include types of outs (groundout, flyout, strikeout), hits (single, double, triple, home run), walks, and special results.
  5. Advance baserunners: Results in parentheses on the card indicate automatic runner advancement. Optional advancement uses the Baserunner Advancement chart.

Continue until 3 outs are recorded; switch sides.
