Steffen-Spiele Ringo (German Import)

Note: This game is in German. For a preview, English rule can be found here.

Four in a row wins!

This victory condition is well known, but Ringo puts a new twist on the concept. The playing field consists of eight rings: four red and four blue. On a turn, the active player places a disc of their color in any ring, then moves the ring to a position adjacent to another ring. Whoever first creates a row of four discs or four rings in their color wins!
