Hedges - the game field is made up of rows and columns of square gardens with a number in each garden. The number represents how many other gardens a person can see while standing in his garden. The object of the game is to remove hedges so that all the gardeners can see the correct number of other gardens.

There are 4 levels of difficulty for each game. The first two levels have 50 and 100 puzzles to solve. The easy levels are good for teaching numbers, math and problem solving to kids age 8 and up. When you play the hardest levels there are 500 tournament puzzles per level and your goal is to complete as many as you can. The results are saved so you can quit and come back another day.
