Let's say a slot is published as 95% RTP. Goes for either online or real slot.

It wouldn't really make sense if the slot is completely random, and the RTP is 95% regardless if the progressive is 100k vs 900k

So, if a slot is published as x% RTP, does that mean x% fixed? As in the RTP of the non-jackpot portion of the game will constantly adjust itself to get lower as the progressive jackpot gets higher.

in video poker, the return % doesn't go down as the progressive jackpot goes up. the #'s (royal, 4 of a kind, flush, etc) are fixed.

dont know about slots but I suspect the 95% would be the base jackpot.
ie: the jackpot reset level

A related question. Are the double up features of slots (not video poker) paying according to 50/50 or the RTP of the slot?

Such as, if a 90% RTP slot has a double up feature, would you expect to win 45% of the time on the double up? or 50%? are there regulations on that? Goes for both online and real slots.

The base game (including the seed/starting amount for the progressive) would be fixed at say 90%, with 5% of every bet going into the jackpot, making the long-term return 95%. In the short term the return could still exceed 100% when the jackpot is high enough, but you'd never know without the math model.

As more bets are placed, the jackpot will increase, as will the "short-run long-term return," which could exceed 100%. But on a larger scale, the return would still be 95% because the return resets to 90% (right after the jackpot is won, before another bet is placed) and can grow to exceed 100% at times.

so lets say a casino advertises 98% return for a slot (Blazing 7's) and .03 is added to the progressive for every \$6 put in.
that's .5% added to the progressive.

so does that mean the slot is set at 97.5%?
(according to Arcade's site, the highest setting is SMI#6894 97.18%)

Sounds right, casino probably just rounded up. Using 97.18 + 0.5% gives 97.68%, which you could advertise as 98%

cool

if the jackpot for that slot resets at \$1000, whats the return % when the jackpot = \$1199.99?
and how did you figure that out?

\$0.03/\$6 = 0.5%

You'd have to know the jackpot probability to figure out its return at \$1199.99.

according to arcade's page, the jackpot is hit approx. every 4096 plays.

at \$3max/spin, then that's 2048 spins for \$6.
2048 * .03 = \$61?!

jackpot will be hit on avg when its \$1061?!
so at that amount, it's 97.68%? ( 97.18 + 0.5%)

every \$61 will add .5%?
so \$1183 = 98.68%??? and at \$1199.99, it'll be 98.82%?
