Stack is a game of skill and technique. The game can be played with as many players as you choose. Stack up the pieces and each person takes a turn removing a block from the stack. Skills such as eye-hand coordination and assessment of stability make this game fun and educational. It can be used also as building blocks. There are 65 stackable rectangular blocks. Each block measures 1 ¼” wide x 3 ¾” long x ½” thick. This handmade game is made of pine and finished with bees wax and olive oil for a safe non-toxic product. These products make these game pieces safe for children. Each piece is sanded with 220 grit sandpaper for a silky smooth finish.
