Space Checkers
Space Checkers is a 3-D variant of the board game Checkers. It was produced by the Pacific Game Company in both  (under the company name "Pleasantime") and .

The earlier version was used as a prop in the food synthesizer room aboard the  on the Original Star Trek. A version was also used in , during which Benjamin Sisko and Jadzia Dax played the game during the "chicken sandwich and coffee" scene.

The game looks to have been released in three versions. The earliest 1965 versions came in a plainer-styled yellow box, and had a red plastic base and clear small plastic boards (see top left). Later versions replaced the clear small boards with those made of the same red plastic as the base. The 1971 release apparently has the same small boards, but was released with a more modernized box design (see top right and lower right).

Gameplay
The game board emulates a cubical 4×4×4 checkerboard (as if a standard checkerboard was cut into four 4×4 sections and suspended over each other). The checkers are initially placed in similar starting fashion to 3-D chess: red starts on the two upper back levels, and black on the two lower forward levels (with the game base acting as the lowest level). Pieces can essentially move and capture as in 2-D checkers (including multiple jumps), with the added effect that moves/captures can also be made vertically between levels (above or below).
