How our games are random — and what "house edge" means

A short, plain-language explanation of how Lucky Rule generates outcomes and why the maths always tilts slightly in the house's favour.

Every round on Lucky Rule is decided by a pseudo-random number generator seeded with sources of entropy that you, the user, cannot predict. We never reach into a round to swing it one way or the other — the generator decides, the result is shown, the round ends.

Because the games are for entertainment, the maths is set so that, over a long stretch of play, the site keeps a small share of total bets. This is the house edge. It is what allows the site to exist; it is not a punishment and it is not a trick. Every casino, real or social, works this way. Knowing the edge exists is the antidote to "I'm due a big win soon" — the maths simply doesn't owe anyone a win.

For a social casino specifically, the edge is irrelevant to your wallet because you cannot withdraw winnings. It only affects how quickly the balance moves, which is the same thing as how long a session lasts.
