Bitz & Pizzas: Optimal stopping strategy for a slot machine bonus game

  • Noelia Oses
Original Article

Abstract

Slot machine games used to be very simple, often limited to just one spin of the reels, but have evolved to accommodate a variety of features that provide added excitement and the potential for greater wins. They also engage the players more by, quite often, requiring them to make choices. This paper presents one of these games, Bitz & Pizzas. This case study introduces a novel application of Operational Research (OR) and serves as evidence that as slot games, and their corresponding models, are becoming more sophisticated, the role of a well-trained OR professional is becoming more important and necessary in this industry. It also shows that OR practitioners are in touch with the needs of the gambling industry and understand current practices and legislation.
