The T puzzle is a very old and challenging puzzle. The puzzle consists of 4 separate pieces which when assembled together make a T shape. It is a very counter-intuitive puzzle. It looks easy but it is difficult to assemble. People often take the wrong lead so it takes them a lot of time to assemble it. And this is what makes it a very challenging puzzle. Here you can see that all the 4 pieces of the puzzle have been assembled into a T. This puzzle has been available commercially for many years. It can easily be cut at home out of wood, rubber or thick card. This is the same T puzzle cut from very good quality wood. And this is how the 4 pieces are put together to form the T. This puzzle can be easily made at home using wood, rubber or thick card. This work was supported by IUCAA and Tata Trust.
