Put Mentagy in your hands:

Some of you may already know that Mentagy was originally developed to help Coach Allyn Kahnís chess students. Allyn used the wooden game board as a tool to explain chess concepts and sharpen his studentís chess skills. Many of his young chess players now sit at the champions table at local club and scholastic tournaments while extremely proud parents watch their children put what they have learned to the ultimate test.

Even if you do not play chess, Mentagy appeals to all ages. More recently we learned that Mentagy is an effective Occupational Therapy tool. The wooden Mentagy puzzle has been successfully used as a treatment for recovering stroke patients as well as others with conditions involving motor skill and cognition challenges. An excerpt of the OTís report can be found on the Practice Puzzle Page.

This original game board is available from this website and it makes an ideal gift for people from ages five to one hundred.


The Mentagy puzzle will make a unique Christmas gift. While the Mentagy book is available at Amazon and other bookstores, you won't find this artistically constructed wooden puzzle anywhere else online. When you give the book along with the wooden puzzle, you are giving someone hours of fun.

Mentagy is the perfect gift for Christmas, birthdays or any occasion, for people who like to use their mind. If you are looking for a gift for someone who likes doing crossword puzzles, playing chess or Scrabble, solving Sudoku, word search, logic puzzles or brain teasers, they will love Mentagy.

A PERFECT MENTAL BREAK (Better than Starbucks!)

This puzzle gives your mind a perfect break during times when you are commuting to work, riding in an airplane, or stuck in a waiting room with nothing to do but read the newspaper or stare at old magazines.

Doing Mentagy puzzles will allow you to occupy your mind with something useful to do, and let you escape from your everyday thoughts about finances, the failing Euro, the stock market, the price of gold or oil, politics, elections, debates, or whatever else the news media is covering. Doing Mentagy puzzles can put you in a mental zone that will actually raise your spirits so that when you solve a puzzle you will feel mentally refreshed, just as if you had a delicious cup of hot coffee.


Remember that Mentagy is great for all ages. Young people enjoy the challenge. Kids enjoy using their minds to figure out the solution. Adults love Mentagy because they know it helps keep their brain sharp.

Doing a Mentagy puzzle every day is a great way to exercise your brain. It is easy to learn the puzzle rules. The Beginner puzzles can be solved in just a few minutes. The harder Mentagy puzzles take longer to figure out. But once you solve one, you will want to do more.

Fabulous Brain Game

Beyond any doubt Mentagy will soon be the new gold standard of brain teaser type puzzles. Daniel Chow
