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.
The game follows standard baseball structure:
Each at-bat:
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.
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:
All other rules follow standard baseball:
The team with the most runs after 9 complete innings wins. If the score is tied after 9 innings, extra innings are played until one team leads at the end of a complete inning.
