The Setting Nobody Reads as a Setting
Speed feels like a matter of taste, and it is presented that way — a small toggle, no warning, no explanation, with the fastest option usually the default. Nothing about the interface suggests that the choice multiplies the cost of an evening by ten, and there is no reason for the interface to mention it.
It is also the clearest example of something genuinely under your control in a game where the widely marketed controls are not. You cannot influence a digit. You can decide how many digits your money passes through in an hour.
The Comparison Worth Running
Play a hundred rounds on a five-minute table and a hundred on a thirty-second one, at the same stake, then compare what each session cost and how long it took. The odds were identical; the experience and the total staked were not. It is the only experiment here that reliably changes behaviour afterwards.
The arithmetic behind those totals is on the house edge page, and every guide is listed on the home page.
