the RTP odds are not SESSION odds.

Who said that RTP odds are SESSION odds?

they are LIFETIME odds for a slot.

LOL! If you start playing slots today and die tomorrow, is one day your LIFETIME odds? Cheesy

And its not per user, but every person that wagers on the slot.

Who said it is per user?

Just because a slot is labeled as a 95% RTP and in 1 session you wagered 100, you're not guaranteed to have a balance of 95

Who said the house edge is guaranteed after 100 wagered?
