From the box: "Stack your logs on the pile in 45 seconds without letting any of them tumble and you score!" The game includes three dice, a 45-second sand timer, and wooden "logs" of three different sizes and colors. On a player's turn, they roll the three dice. The color and number of each die tells how many logs of each color must be added to the stack. The player has 45 seconds to add them without wrecking the stack or having any logs roll off.
