Education, not advice
notluck shows what gambling costs on average over time. The calculator and articles are for education only. They are not financial, legal or gambling advice, and they are not a prediction of what will happen to you in any session.
Estimates
The expected loss is exact for the house edge you enter: it's simple arithmetic. Everything else is an estimate. Real games differ from the presets: a slot's actual RTP depends on the version a casino chose, table rules vary, and the speed of play depends on you. The lucky and unlucky ranges are statistical approximations, and the sample sessions are random simulations. Each page lists its sources and says which figures are estimates. See how the numbers work.
