Osman hits a button on his table, activating a round generator, which is displayed on a big screen.

The fourth round is typically "slow", where the question takes several minutes to be answered, and only one contestant receives a single point each time.

At the end of each day, the scores are announced and the winner wins a daily prize, which is usually a normal everyday object of some description with the "House of Games" logo imprinted on it (the logo being a turquoise-blue background with a depiction of Osman's hair, eyebrows and glasses).

Starting with Series 3, special "House of Champions" episodes aired featuring players who had previously won a daily or weekly edition of the show coming back for another week to fight for the Gold Champions Trophy.

In Series 6 and 7, there were also special "Redemption" weeks with four previous losing contestants who had never won a day prize.
