How a casino earns. Every casino game is designed so that, over many bets, the casino keeps a small share of all the money wagered. The industry calls this the house edge. On a slot machine, the software sets how much of the money played is paid back to players over time. A random number generator, a program that picks results by chance, decides each spin. Regulators test and certify this software before a machine may be used.

A casino floor runs on slot machines, cashless wallets and table-game technology, all tracked by the casino management system, while regulators certify the software and the house edge keeps a small share of every bet.

How a lottery runs. Many governments run lotteries to raise money, and hire a company to run the systems. A central system records every ticket sold. Terminals in shops sell tickets and pay prizes. Instant tickets, the scratch cards that show at once whether they have won, are printed by the millions. A large national lottery handles millions of tickets a day. Contracts to run a lottery often last ten years or more.

A government hires an operator to run its lottery: a central system records every ticket, shop terminals sell tickets and pay prizes, and instant tickets are printed in bulk.

A heavily regulated business. Casinos and lotteries need licences, and regulators audit them closely. They must watch for players who are losing control, and for money laundering: using gambling to make criminal money look clean. (More on how money laundering is caught in Market Segment 19.2, Fraud prevention, AML and regtech, in Industry Vertical 19, Banking and regtech.)
