发明名称 LOG LOADING CONTEST
摘要 A game for testing the skill of operators of log handling equipment which includes an articulated boom with log handling grapple positioned relative to two spaced grid areas. The grid areas are in a diamond arrangement with the squares of the grid areas being checkered, e.g., black and white sets of alternating squares, and one set of squares, e.g., the black squares, being designated as log holding squares and the other set being off limit squares. At the outset, the log holding squares of one grid are provided with log sections and the object of the game is to move the log sections from the log holding squares of one grid area to the log holding squares of the other grid area in the shortest possible time.
