Well welcome to the group, miotti! For going about learning Video Poker, I'd say that the first game that should be learned is specifically called "Jacks Or Better" -- specifically the one that has the pay schedule of 9 For 1 for the Full House and 6 For 1 for the Flush. But don't let this 9 and 6 pay schedule fool you. You may find other Jacks or Better variant games like Double Bonus or Double Double Bonus Poker where the 9 and 6 pay schedule can be BAD (too low returning and too volatile).
There is a Video Poker training computer program that you can now download onto your computer for Free. It's called "Frugal Video Poker" by Jim Wolf and Jean Scott (who's also known as "The Queen Of Comps"). To get it, go to: https://www.wolfvideopoker.com/FVP.htm. The game's programmer, Jim Wolf hopes that people might buy other of his newer products (but you're not forced to).
And another place online where you can practice and it will tell you if you're making playing strategy errors is on the Wizard Of Odds website at: https://wizardofodds.com/play/video-poker/. It deals with 9/6 Jacks Or Better Video Poker.
Another good source for written Video Poker information is the American Casino Guide website which is at: https://www.americancasinoguide.com and then from there, go to their Video Poker link. And check out the website's Gambling Podcasts link for all of the Video Poker stuff. And the actual American Casino Guide Book (get the 2013 Edition), has some very decent coupons as well where you can recoup most if not all or even more than the purchase price.
And as for Video Poker machine locations not only around Las Vegas but around the United States and Canada as well, besides the https://www.vpfree2.com website that was mentioned earlier, there is another website (that you have to get a paid subscription to) that has good information as well. That's at: https://www.vpinsider.com.
I'd also recommend Video Poker books by Dan Paymar (at: https://www.optimumplay.com). And he also has (I believe) a demonstration version of his Video Poker game (which is called Optimum Video Poker) that you can download. And while at this website, check out and maybe print out his FAQ (Frequently Asked Questions) link!
And another important thing to do when learning this game is to make sure that you always keep in mind the exact order of every Straight (and Straight [Or Royal} Flush) possible (that's: A-2-3-4-5; 2-3-4-5-6; 3-4-5-6-7; 4-5-6-7-8; 5-6-7-8-9; 6-7-8-9-10; 7-8-9-10-J; 8-9-10-J-Q; 9-10-J-Q-K and 10-J-Q-K-A).
Enjoy!
