Who Wants to be a Millionaire Slot Game
Developed and released in 2016 by Australia-based developer Big Time Gaming, Who Wants to be a Millionaire is one of the UK online slots based on the classic game show of the same name, and this title comes with a whole host of bonuses and features! It is also BTG's first branded slot game.

Who Wants to be a Millionaire Game Background
The Who Wants to be a Millionaire slot faithfully recreates the game show setting down to the most minute details with the studio floor and audience seats all present and accounted for. Between spins, the ambient lighting is moody and dark, the music ominous and mysterious. Spin the reels, however, and the music transforms and becomes flashy and upbeat, although with the same dark and ominous undertone. Land a winning combination on the reels as well, and the spotlights start to go off, flashing in tandem as they do so.
