A phone-in game show is Exactly What It Says on the Tin. It is a logical extension of the concept of a Home Participation Sweepstakes, except in this case, the whole show is one. These are a form of live Game Show where viewers can call in to a special number and hopefully get a chance to come on air to potentially win something by providing an answer to a question or logic puzzle. They were quite popular in Europe as a fixture of late-night television on commercial television channels, and even on dedicated quiz channels that dedicated their lineup to just this genre. If done right, they can at least be fun to watch, and leave you wondering if you should even phone in and give it a shot yourself!
