How casinos actually make money

Time saverEvery game has a built-in house edge. The casino earns a small percentage of every bet, and volume makes that percentage reliable. Bonuses, comps and design all push you to play more rounds.

ProStrategy6 min

Bankroll management and the Kelly criterion

Time saverKelly says stake f = (bp - q) / b where b is net odds, p win probability and q = 1 - p. If the result is zero or negative, do not bet. Most pros use a fraction of Kelly to cut variance.

BeginnerIndustry7 min

Why casinos are colorful: the science and the spin

Time saverBright colors, sound and light are used to hold attention and make play feel rewarding. Some effects are well documented, such as near-misses and losses disguised as wins. Others, like specific colors, have mixed evidence. Knowing the tricks helps you stay in control.
