The minigames can be selected, you can pick which groups you want to include/exclude and I think there are like 4-6 categories (Luck, Skill, Family-Based, etc.)
If you want to give people a better chance of winning the game at the end then I would consider these options: 20 Turns, All Bonus Stars (do not select Classic Bonus Stars), select and omit your minigame groups of choice, consider giving a handicap/boost/head start to some players. The default (All Bonus Stars) allows anyone a decent chance since there are eight possible stars that can be selected. I’ve had some very close games and absolute shockers when playing w/ All Bonus Stars (as opposed to Classic Bonus Stars)

in my experience the game is best when your family and friends begin to master the game. It’ll come with practice, as long as you guys play like once a week or so you’ll all be great players fairly soon. The real upsets begin when all players recognize how to compete and make the most of their turns, can win minigames. But here’s another thing I’ve noticed, winning minigames is not always as important as one might think, I’ve won a few times without having the minigames on my side; was like 2nd or third best in that category. If you are getting bested in minigames, there are usually some areas with more Lucky Spaces. One example would be on Yoshi’s Tropical Island, on Watermelon Island. There are plenty more Lucky Spaces on Watermelon Island than there are on Cantaloupe Island. It’s all about knowing the boards, navigating the map with precision, making sound choices that maximize your chances of success and competing hard each minigame to will your character to victory. These minigames are tough, even I’m being rigorously challenged with many of them, and I’ve played these games constantly over the years
The more you play and learn the game, the more fun each game becomes. That’s why I would strongly suggest that each player look at each board and study the maps, practice the minigames and come up with certain tactics and strategies that you can rely on, and that will propel you towards greater odds of purchasing a Star, winning a Bonus Star, gaining some Coins and/or Items, etc.
One more tip, you can add turns to a game. If you think someone is struggling and could use some more time then you can always add some turns before you reach the last five turns of the game. You just have to press start and the option to add more turns is there for your party. A lot can happen in five or so extra turns; a lot can change
