notluck is a free calculator that shows what gambling really costs over time. You choose a game, a stake and how often you play, and it shows what the house edge adds up to, for lucky, average and unlucky players.
Why it exists
Casinos, sportsbooks and the sites that promote them all talk about winning. Almost nobody shows the other side: that every game keeps a small cut of every bet, and that this cut adds up to a predictable cost if you keep playing. notluck shows that number, in plain language, with the maths and sources visible.
It isn't here to judge anyone. Plenty of people gamble for fun and keep it under control. Knowing the real price helps you decide how much fun is worth paying for.

How the numbers work
House edges for table games come from the rules of each game. Slot RTPs, speeds and other figures come from regulators and published data, and each page lists its sources. Where something is an estimate, the page says so. Read how the numbers are built.
