What is Futoshiki?
Futoshiki (不等式 futōshiki), or More or Less, is a logic puzzle game from Japan. Its name means "inequality". It is also spelled hutosiki (using Kunrei-shiki romanization). Futoshiki was developed by Tamaki Seto in 2001.
It's not magic, it's math.

Homeschooling / Parochial / Public / College Teachers:
This is a perfect and fun beginning book for learning inequalities.
The puzzle is played on a 5 x 5 square grid. The objective is to place the numbers (1, 2, 3, 4 and 5) such that each row and column contains only one of each digit. Some digits may be given at the start. Inequality constraints are initially specified between some of the squares, such that one must be higher or lower than its neighbor. These constraints must be honored in order to complete the puzzle.
Why are inequalities important?
As a college math instructor, I have many students that are still baffled by the inequality symbols! Inequality also in connected to rounding, and I have calculus students that are terrible at rounding!
Start your student off right with this series of books!
Math isn't magic, it fun!
