An action game in which a plurality of elongated playing pieces are placed in upstanding condition on a game board in selected positions in an attempt to form a continuous unbroken line of playing pieces from one player's king playing piece at a playing station at one end of the game board to the opponent's king playing station at a playing station at the other end of the game board. If the playing pieces are properly set in such line and are properly oriented with relation to each other, the pushing over of said one player's king playing piece will cause the playing pieces in the line to topple over successively, each striking the next playing piece, in a chain reaction of cascading playing pieces, at the end of which the opponent's king playing piece is toppled. The playing board contains a pattern of spaced cells into which the playing pieces are inserted, the cells being staggered and arranged so that no straight line of cells extends from one player's king playing pieces to the other player's king playing pieces. Each cell is so configured that a playing piece may be inserted therein in any one of three preselected directions. Each playing piece is formed with a pointed, angular upper end, permitting the chain reaction of toppling playing pieces in the line to turn corners.
