Red/Green Cancellation

Most of our activities work fully with red/green glasses and visual suppression techniques. We have developed new techniques and colors to revitalize a tried and true technique.

Our games work great without using the red/green feature, too. As a registered user, you can try any activity before assigning it to your student. Here are a few snapshots to show our cancellation. If you need other samples, contact us. We are always happy to help.
