Do casinos have any say in changing House edge?

Not on this site's evidence. A value behind house edge that comes from the game's own mathematics belongs to the studio, not the operator; with no figure from the studio, no outside source can establish it.

House edge has an exact meaning, and the loose version of it causes most of the confusion that surrounds it.

House edge — What the operator holds as its mathematical advantage, and the arithmetic complement of RTP

House edge is 4% when the game’s RTP is 96%. Rather than a fee taken at the end, that 4% is built into the odds of every outcome, which means it applies all the time, whether the player is ahead or behind. A negative expected return for the player in a commercial casino game is deliberate, and this explains it.

The common misreading

There is a claim that a system can beat the house edge. It is not. Whatever pattern you stake in, the probability of an individual outcome stays the same, and that is where the edge sits. The expectation is untouched when you double after a loss; what moves is the distribution, with larger, rarer wins and a catastrophic tail.

What the operator earns from a player as margin is a different matter, and so are fees, from the house edge. It is a long-run statistical property. A game is not proven unfair by it either: a disclosed edge is how the product works, and no edge would leave the operator with no business model.

Using it in practice

Over time, expected return is negative in all commercial casino games because of the edge. A more accurate frame is to fix the expected loss in advance and regard it as the price of the entertainment, not as an investment gone through a bad month.

Game pages here keep using terms like House edge; if the studio leaves the figure behind one unpublished, the pages state that rather than borrowing a number from a comparison site. As a result, you’ll see a few spec tables here with unfilled fields.

A worked example

The expected loss is ₱200 when a 4% edge applies to ₱5,000 of turnover, however wins and losses fall in sequence. Deposits are not the measure, turnover is — a player depositing ₱1,000 and cycling it five times creates ₱5,000 of turnover and the same expected loss, though only a fifth of it was deposited.
