Futoshiki

I am dead impressed by this puzzle I discovered recently, called Futoshiki. It could be used after a lesson on inequalities to reinforce the meaning of the symbols, and also aid the development of logical thinking via problem solving.

An example of a puzzle is below.

Some links to good online Futoshiki sites are below:

Japanese Logic Puzzles

I love puzzles, and a fantastic website is www.conceptispuzzles.com which contains lots of interactive Japanese logic puzzles.

Enigma puzzles are based on the following rules:

  • Link each number to another of the same number by the same number of squares (ie. pair up same numbers) by drawing a pathway.
  • No pathways can cross and no numbers can be used more than once.
  • Shade this pathway so that the result gives a picture.

An example called “Batman” is shown below, and has been taken from www.conceptispuzzles.com

batman_puzzle and batman_solution are pdf files you can print out nicely of this puzzle.
