This is a dice game, with a baseball theme, from the 1950s, which uses two special dice.

From the card that comes with the game:
"B-B Ball Players Baseball Game - Everything Real but the Umpire. 9 innings - 9 minutes. Anywhere. Anytime. 2 to 18 players. Nu-process Parlor Dice Game."

The rules are stated in a few lines:
"Same as baseball.
Batters cast dice in turn until a play is made.
A pair (2 of a kind) is a play.
No pair is a strike.
Double play when 3 OUTS are shown."
