Sumdog's 3D games and games with Spelling questions are made differently from other Sumdog games. They run using WebGL which needs up to date browsers to work properly.
Internet Explorer does not support WebGL.
You'll need one of these browsers:
|Browser||Minimum version||Link to download the recent version|
|Chrome||22.214.171.124 or later||Chrome|
|Firefox||52.0 or later||Firefox|
|Edge||16.0 or later||Edge|
|Safari||11.0 or later||Safari|

If you are still having difficulties running Sumdog 3D games, your operating system or hardware might be struggling to run WebGL. Try using a different computer or download one of our apps.
|OS||Compatible with||Link to download|
|iOS||iOS 9.0 or later||Download from the App Store|
|Android||Lollipop 5.0 or later||Download from Google Play or the Amazon App Store|
Please note the first time you open a 3D game, it will take a little time to load the game engine. Please allow a minute or two, even if it doesn't appear to be loading.
