Italy's La Ruota Della Fortuna

Most entertainment programs feature one or more telepromozioni, promotional segments where sponsors advertise their goods.  In Italy there's a limit to how much advertisement a network can air, and those segments would be technically  part of the show and would not count towards their quota.

During gameshows they usually took the form of miniature games. Players usually were phone-ins or randomly selected audience members.

Rarely the sponsor game used the same contestants from the main game.

Sometimes they were simple luck-based games, other times they were more elaborate, complete with a bonus round and a progressive jackpot.

I remember one of those games was bringing bouillon cubes from a car trunk to a scale, and another was about doing math while running on a treadmill

The rules have changed since, and now telepromozioni cannot use elements from the main program, so no mini games anymore

Another interesting outtake, this time is from the first episode of season 2

Mike's third son Leonardo was born a few days before this taping

Before the taping starts, Mike has some instructions for the audience

---

Quiet, quiet

OK. Thanks, you are very kind for this applause, I hope it's addressed not to me but to little Leonardo.

I don't know how many of you already attended Wheel of Fortune, I think some of you already attended, you came the last year, or never?

Then you know how this game works?

Well, it takes much enthusiasm, you have to cheer for the contestants as they guess letters, as they win their prizes; of course you can incite them by calling their names, "go", "here", "there"... you can even whistle, do a bit of everything because this is a show that needs a lot of movement and, I'd say, a lot of enthusiasm. Logically you must not exaggerate too much; the applause, when you notice that the contestant is already moving to spin the wheel, then you must end it, but I think that our studio assitant will tell you when it's the moment to diminish the applause, because otherwise we couldn't hear each other while we are talking and you are applauding.

Well, now we are doing a proper test applause for Mario Bianchi because I think he wants to hear how it comes out. Just a little moment.

Well, for now we'll tape, hopefully, if everything goes right, four episodes. We'll tape a couple now and then I believe there's a switch, because not all of you do four episodes, I think you do 2 and 2 if I'm not wrong. Then possibly we'll do the other two after lunch break, I immagine, unless you stay with us until the end; in this case we'll stay together until 11.

Anyway, I think it will be fun... now let's do this test applause and let's see how it comes. Ready, go!

Mario, how's that?

MARIO: Yes, if you do a few more whistles it doesn't hurt

Ok, all right

MARIO: If you cheer for the contestants, with their names...

All right, enthusiasm of course. Every once in a while you'll be in the frame, so make a nice smile when you are in the frame, alright?
Mario, where are the contestants? Did you summon the contestants?

MARIO: Yes, a moment

Then... you know where to position yourselves... alright, I'm here. Where's Paola, is she there? Is the model there? The two contestants that are playing for that are there....

[Mike is now talking to Paola Barale, the new letter turner. Mike here is talking about the sponsor's mini-game that involves two contestants from the audience playing a game of chance for a new car]

Alright Paola, do you know what we have thought? In the case of a tie we won't do the cards but we'll give the prize to whoever has the most pairs. I mean, if they stand three-three and then one has two pears... got it? And the other doesn't have them, then that one wins. Let's try this, let's hope it works, if it doesn't work we'll do another round, right?

ASSISTANT: OK Mike, when you want...

Yes.
This is to be thrown away... paper.

[Next, the returning champion asks Mike if they can congratulate to him during the show. Mike refuses because he probably broke the news on his other shows, Concentration and Jeopardy!, and he doesn't want to bore the audience. unbeknownst to him, the first puzzle of the day will reference little Leonardo]

RC: Mr. Mike?
Yes
RC: I wanted to congratulate you for the birth of Leonardo, in association with the other two contestants, so...[?]
I don't know if it's the case, no, no... let's not talk about it because we've already said before. Maybe I'll tell about it when...[?].
I mean, we already went on the air for more than one week with other things...[?]

"Ruota Story" is a fancy title Mediaset gave to their Summer reruns of Wheel, they don't contain Odeon episodes

Regardless, it's interesting to see how the format changed:  the 1994 one was a classic-rules episode (with the warm-up lap), in 1996 the show tried all the gimmicks (a bonus question after every puzzle), the two 1998 episodes are the tournament of champions final, played over two days probably because Mike watched Jeopardy! and liked the idea.
