Hexa Trex... Comments
Here are some comments we received from people that have played Hexa-Trex:
"This is a very good game. From a psychologists perspective, one can see how a child needs to use their spatial skills to find the equations. This puts a challenging spin on regular arithmetic." Anna Mroz, Professor of Pedagogy and Psychology
"Fun game. Easy to learn, challenging to play and win." Jenny Chao, PhD in Engineering
"As an educational tool your Hexa-Trex product is an excellent activity... its elaborate diagonal equation pathway is relatively sophisticated when compared to the more basic "unsupervised" number games..." Andrew Berton, Games Reviewer
"These puzzles look like a lot of fun for whole number and integer arithmetic review. I think they would make a great warm-up at the beginning of a class or math club meeting." Denise, Author of Let's Play Math blog
Neat Puzzle
Came across your site today. I really like your puzzles. They're a little like Sudoku, where they seem hard at first, but then you begin to see some patterns in them and develop little heuristics to solve them.
I do have a suggestion: Definitely don't allow repeating of hexes.
Also, see my comment on yesterday's puzzle: http://www.nucleuslearning.com/node/76#comment-9 for another answer using different numbers (versus just exploiting the trivial commutative properties of equality and addition).
