My Take
This is not a teaching tool; it is a game that could be played at recess. The organization of the site is confusing and not student friendly. There are ads before every game that could lead to misclicks and lead them astray from the games.
How I Use It
This is a program that you can reward your students with if they finish their math early. However it is not an enrichment tool that continues to push your students mathematically. This tool is filled with arcade games that do not mathematically challenge your students as much as it makes them strategize. It worked as an incentive but not as a math tool.
