"Slot machines are the bread and butter of the casino industry, accounting for three quarters of casino profits. All slot machines are pre-programmed to keep a portion of the cash put into them."

"Two different roulette wheels exist: European wheels which have 36 numbers plus a single zero and a house edge of 2.63% and American wheels which have a zero and double-zero and a 5.26% casino edge."

"Dealers are prohibited from making any direct transactions with players. You must place your money on the table where the dealer will convert it to chips and place the chips in front of you."

"Slot machines have been around since 1887 when San Francisco inventor Charles Fey built a machine featuring three wheels decorated with symbols like diamonds, hearts, and bells, which triggered the jackpot."

"Casino results are expressed as probabilities, usually as a decimal amount between zero and one where zero is impossible and one always happens. For example, the chance of a flipped coin being tails is 0.5."
