Thanks to a post here about "Letters and Numbers," the Australian version of "Countdown" which is being aired by SBS, my family and I have been enjoying the episodes posted online. Even the kids were getting into it (although sometimes because their dad could not come up with a reasonable word, or solve the "Word Mix" coming in and out of breaks).
Unfortunately, it appears that SBS is geoblocking the Episodes past #12, and might be getting around to geoblocking the earlier episodes that we'd already watched. (The series is up to #20 at this writing.) What I get when clicking on an episode is "Geoblocked" and the message "This video is not available in your region".
I know that SBS doesn't get any ratings bump from a family watching here in the USA. Or perhaps they are not licensed to allow their version of the game to be viewed outside of Australia.
At any rate, it was certainly a fun show to watch -- good while it lasted. My wife and I honeymooned in Australia almost 20 years ago so we have a particular affection for the country and it was great to enjoy a little bit more from "down under."
My main point is to thank those here on the board who mentioned that this show existed so that we had a chance to watch when we could!
