Hand crafted from hardwood the 38 piece hand held version of Mentagy measures just over 6" x 6". To play simply mark the blank spaces with the black pegs and seed letters with the red letters. You're now ready to use the remaining white letters to solve the puzzle. One advantage of the wooden Mentagy ™ set is that you can solve the puzzles without using an eraser. If you are in the middle of solving a puzzle and have to stop, you simply place the top on the base and the pegs cannot move. Take the Mentagy ™ set anywhere and continue where you left off.
