Most of the time, if a user is having trouble using PatternJam it's due to the device or browser they are using:
•PatternJam is NOT optimized for use on a phone. Also, some tablet devices do not work well with PatternJam. It's recommended that you use a computer when working with PatternJam.
•If you find you are having trouble with PatternJam, even when using a computer, try using a different browser. We recommend using Google Chrome for PatternJam.
