Ringo is a two-player strategy board game from Germany,[1] invented perhaps in the late 19th or early 20th century.

The circular gameboard consists of six concentric rings divided into eight radial segments, and a central citadel, for a total of 49 spaces of alternating light and dark colors.

The player who is the attacker initially controls seven pieces (black or dark color) that start one per space on the outermost ring (but not in the neutral zone).

The player who is the defender initially controls four pieces (white or light color) that start on the four light-colored spaces of the innermost ring (also not in the neutral zone).

"Black should make use of the neutral zone to organise an assault on the citadel in safety.
