Really super buggy...using Chrome on Mac 10.7...letters get stuck all the time, sometimes keys don't register...needs work, but looks like an addictive concept, if I could make it through one round without it misregistering my keystrokes...
For what it's worth, I'm using Chrome on OS 10.7 and it works flawlessly.
He might be unaware that letters need to be inline. I ran into that at first when I thought I could use any of the letters on the board whether they were adjacent or not. Once I learned the mechanics, it stopped 'acting buggy'.
