EZ GRYB (2001)

EZ GRYB (aka Quick & Easy GRYB) is an introductory game for the GRYB Game System, which uses the tetrahedral GRYB die and allows captures. The goal of the game is to form a GRYB on a single quadrangle. Each turn, you roll the GRYB die, which dictates the color to which you must move a chip, either by introducing it to the appropriate node of the top quadrangle, by moving it down a level to the appropriate node of the lower quadrangle, or by moving sideways to capture an opponent's chip on an adjacent node on its current quadrangle.

EZ GRYB was published in the instructions for GRYB Game System 2.0.
