The edge, not an estimate
Video poker was checked by enumerating all 2,598,960 deals. Where a published figure existed, ours matched it. The method for every game is on the methodology page.

Comps
What your play is actually worth
Loyalty programs priced in dollars of play rather than points, on land and at sea. Several of these charts exist nowhere else in readable form: the lines publish them as untagged images, so we transcribed them and graded every figure by where it came from.

- Princess Sea You Soon chart All nine rungs across four voyage lengths, published as text for the first time.

How we know the numbers are right
Anyone can publish a house edge. Here is where ours come from, and what a single session actually looks like next to one.
Comps figures graded by origin
Cruise earn rates come from the lines' own material or first-hand reports, and each is labelled with which. Where a line publishes nothing, we say that rather than guess.
