Additional Note[]
The Italian, Serbian and Turkish versions are based on the short-lived 2006-2007 GSN version from American (with the exception of the Italian version mixing two formats of Chain Reaction along with the unsold game show pilot Combination Lock). While the Canadian (French language only), Indonesian and British versions based their formats on more or less of the 1980 and 1986-91 NBC & USA Network/Global versions respectively.
