Overview

All-Star Baseball is a classic spinner-based baseball simulation game first released by Cadaco in 1941. Designed by former MLB player Ethan Allen, the game uses circular player cards placed on spinners to simulate at-bats. Each card is a statistical pie chart reflecting a real player’s actual hitting percentages. The game follows standard baseball rules — 9 innings, 3 outs per half-inning — with the spinner determining each at-bat outcome.

Components

Setup

  1. Each player drafts or selects a team of player cards.
  2. Set the batting order for each team.
  3. Place the game board centrally.
  4. Set the score to 0-0 and prepare to track innings.

Turn Structure

The game follows standard baseball structure:

  1. Visiting team bats (top of inning)
  2. Home team bats (bottom of inning)
  3. Repeat for 9 innings (with extra innings if tied)

Each at-bat:

  1. Place the current batter’s circular card on the batting spinner.
  2. Spin the spinner.
  3. Read the numbered section where the spinner stops — this determines the outcome.

Actions

Batting (Spinner Results)

Each circular player card has numbered sections of varying size arranged around its circumference, forming a statistical pie chart. The spinner result numbers correspond to:

Number Result
1 Home Run
2 Ground Out
3 Ground Out
4 Fly Out
5 Triple
6 Fly Out
7 Single
8 Ground Out
9 Walk
10 Strikeout
11 Double
12 Fly Out
13 Single
14 Ground Out

The size of each section varies per player card based on the real player’s statistics — a power hitter has a larger Home Run section, a contact hitter has larger Single sections, etc.

Baserunning

When runners are on base and a hit or walk occurs, the second spinner determines how runners advance. The fielding/baserunning spinner shows zones that indicate whether runners:
