About this Site

The Problem Site provides a wealth of free online educational games, including math games like Adders!, which helps students practice their addition, subtraction, multiplication, and division facts, as well as One to Ten, which encourages problem solving skills as students try to combine four digits with the arithmetic operators to form all the numbers from one to ten.

Beyond all the math games, there are also many word games, including our Hangman game with an enormous vocabulary list, our ever popular Scrambled word game and Secret word game, and our telephone game and blackberry game.

But the fun doesn't stop there; there are also many fun strategy games and quests, like Entrapment, our geometry based dot-trapping game, the deeply perplexing Treasure Hunt, our fun physics game, and a two-player game of Connect Four in Zero Gravity

And for those who have younger children, there are also our Junior Edition Games, which are designed for children who find our other games too challenging. Professor Puzzler helps children learn about spelling, estimation and more!
And that's just the games! There are also math problems, brainteasers, printable worksheets with jumbles and word searches, a multitude of reference pages, including our popular codes and secret messages pages and our Educational product reviews.
If you get the feeling that we're just scratching the surface, you're right! You can spend months exploring this site and not cover all the fun and educational resources available free of charge!

The Problem Site is a free website designed and maintained by Douglas Twitchell, who is also a math and science teacher at Oxford Hills Christian Academy.
