Feature on the slots in Melbourne

That's the Melbourne in Australia, not the one in Florida.

Anyway, I was at Melbourne's Crown Casino (for some reason, there's plenty of roulette, baccarat, and card games to go around, but few craps tables, and zero video poker), and I noticed that all of the slot machines (well, they call them "poker machines", or "pokies", mainly because they have A, K, Q, J, 10 instead of fruit symbols - and pretty much all of the machines are the 5 reels x 3 visible rows variety) had a surprising feature; if you went through enough of the on-screen information screens, the machine displayed its expected return percentage. I was a little surprised that the dollar machines only had about a 93% return (the penny ones tended to be somewhere around 85%, I think).

(I didn't see any progressive machines; if there were any, they may have been limited to the "members only" high-rollers area.)

Something tells me I'm not about to see this coming to any Vegas casinos any time soon (especially as it seems to be limited just to Melbourne; the slots at Star City casino didn't have this).
