Hey Jester, great minds think alike! This is something which we will introduce over time, along with some other nifty features ;) Watch this space! And thanks for the feedback, it's always appreciated. Awesome :D Thanks for the info Leo!
Glad to see I'm not the only one who failed to notice the effect of those tiles. Gold tiles don't have a value, but will x2 the value of the word that it is used in. Silver tiles x2 the value of the letter and blank tiles have no value at all apart from being extremely handy in times of need of course!
Have you tried the regular troubleshooting yet? Make sure you have cleared your cache and that you have the latest version of Flash player installed. Not having anything else running in the background should also help it load.
If you've made a purchase i'd get in touch with them via the link below, If you attach the receipt and stuff it should get sorted a bit quicker. http://help.king.com/contact
