It looks like you're running Safari. We're very sorry about this, but we can currently not support Safari in Idle Raiders, because the way Safari handles cookies prevents various Idle Raiders features (like logging in at all) from working. Please try the game with another browser!
The following browsers are officially supported:
Chrome (latest versions)
Firefox (latest versions)
Internet Explorer 11 and later
Microsoft Edge ("Internet Explorer 12") and later
Your browser could not initialize WebGL. Idle Raiders requires WebGL to run. Make sure your browser supports it. You can check using the support table at http://caniuse.com/#feat=webgl .
If your browser is not listed as supported (marked in red), please update to the latest version of your browser (or a different browser).
If your browser is marked in green, but you still see this error message, make sure you have not disabled WebGL in your browser settings.
