Is says "Cannot read property 'getParameter' of undefined".

What build do you have: Windows, Mac or html5 (browser)? Did it just start up or were you playing for a while? And lastly, what were you doing in the game before the error message?

In browser (Chrome). Appears after loading bar.

I've tried replicating the bug in Chrome on Windows and Mac with no success. What version of Chrome do you have? If it's not up to date, try updating it. Please send your reply to ianschiffmangames@gmail.com with the header "Gridlock Solitaire Bug".
