*Breakthru - a modernized version of medieval Tafl*
Breakthru was designed by Alex Randolph and commercially released by 3M
Company in 1965, as part of the 3M bookshelf game series. Breakthru has
much in common with the Tafl games of the Middle Ages, such as Hnefatafl
or Alea Evangelii, as there are unevenly matched teams with different objectives (cf. Wikipedia).
