Love this show. Watched it like crazy back when it came out in 2006 and 2007 when I was in middle school. I have always loved word games. Glad to see it here again.
this game show in italy called "reazione a catena" the manches called "una tira l'altra" (each zip correspond in € 10,000 and 20,000€) and "l'intesa vincente" (much more killer in italian version)
