DuploLine is 4-in-a-row game that includes two different types of pieces (discs and rings). The goal for each player is to make a line of either four (or more) discs or rings of their own color. DuploLine is a very tactical game derived from the designer’s more strategic DuploHex. Although both games use the same types of pieces and similar rules, the different goals and the small variations in the “adding” and “moving” mechanisms make DuploLine and DuploHex two completely separate games. MATERIAL - A hexagonal board with four hexagons per side - 18 white discs and 18 black discs - 18 white rings and 18 black rings
