Top 10 Worst Mario Party 7 Minigames
Mario Party 7 has the largest collection of minigames in the Mario Party series, with 88 in total (not including Mario Party: The Top 100). It also features one of the most diverse selections, including Free-for-All, 1 vs. 3, 2 vs. 2, Mic, Bowser, DK, Rare, Battle, Duel, and even 8-Player minigames!This game also has one of my favorite collections of minigames. However, there was a small number of REALLY bad ones, especially from the categories that were new to the series.
With that being said, here are the worst ones.

Bowser's Lovely Lift, oh yeah. This is one of the absolute worst final boss battle minigames ever created and one of my least favorite minigames ever.
It's not that it's bland or simple. It's that it's way too hard! In fact, I still haven't beaten it despite owning the game for four years. The annoying difficulty is primarily due to poor controls, as you can't jump very high and the speed is very tight. You need to hit all the buttons on a lift to get higher, but Bowser shoots missiles at you at the same time, making it hard to avoid them.
What's worse is that you only have one hit point. If you lose, you not only need to start the minigame over again but also find a new star on the board! I still have not unlocked Bowser's Enchanted Inferno because of this. By far, my least favorite as a result.

Mario Party 7 introduced these "DK" and "Bowser" spaces, which would occur if you landed on their respective spots. I hated this concept because the turns took way too long as a result.
What's worse is that they aren't even that good, at least not the single-player ones. The worst one is by far the single-player DK minigame, Vine Country. Here we have the precursor to Mario Party 8's Flip the Chimp and Mario Party 9's Chain Event. How does it compare to those?
I'd say this one is the weakest, which means I think it's actually worse than even Flip the Chimp. Why? Let me ask you this: do you prefer shaking the Wii Remote or button mashing? I prefer the former, but that's not the only problem. You also need to play perfectly and not hit a single thing, or else you'll lose, as your opponent DK always seems to be slightly ahead of you.
I loathe this minigame on so many levels.

Like DK, Bowser has his own minigames which are activated whenever you land on Bowser Space. It's either multiplayer or single-player, and the absolute worst one here is the multiplayer minigame, Funderwall.
This one is so annoying. You basically climb up a cage while Koopa Kids spit fire everywhere, making it too hard to avoid. I don't like this one at all.

This minigame gives me pretty bad memories of Random Ride from Mario Party 5. On a side note, it's not RNG at least and actually requires skill.
But it's so poorly explained how you're supposed to play this minigame that I never seem to get the hang of it, not even after practicing for ten minutes straight! You're supposed to fly the farthest distance with a pair of wings by tilting the control stick from left to right to gain height, but I can never get further than the Easy CPU. This minigame is just annoying.

Hot take: I don't dislike the Gamecube Mic at all. In fact, I thought it was a really neat addition to the Gamecube, as it's super comfortable to hold and use, even if it's not that responsive.
Speaking of not being responsive, Dart Attack is the least responsive Mic Minigame. You all take turns shooting arrows at signs with points that go left to right, and you shoot by saying "Fire." However, it doesn't fire until two seconds later, which can get irritating when you think you have it but the timing ruins it. I don't like it.

Would you look at that, we have the precursor of my least favorite Super Mario Party minigame, Bob-Ombic Plague. There have been many different versions of Hot Potato in Mario Party, but this one takes the cake for being the absolute worst.
As an 8-Player minigame, you all throw the bomb to each other. However, whenever it explodes, it won't just eliminate the player holding it but also the players next to them. Just...WHY? It removes all strategy from an already luck-based and random minigame that wasn't fun to begin with.

This is a minigame with a good and interesting concept, which was terribly ruined in the execution. Basically, a notebook with animated pages appears in the middle, and the player has to replicate that same picture in their notebook by pressing L/R to go forward in the notebook animation.
However, it's incredibly unfair because it takes ages to move just one page. Some people have an unfair advantage because their page is closer to the right one in the middle notebook, allowing them to get to the correct page faster. It's just really unfun to play.

Let's be real, who even likes slot machines? This is an 8-Player slot-machine minigame where two players each take care of one half of a spinning slot machine. The two halves must match (one is the underside of a Goomba and the other is the top half) to earn points.
I never liked any of these slot minigames, and this one is just as bad.

I've never liked minigames where you need to catch stuff falling from the sky, and this is no different. Here you must get as much honey as possible dripping from the sky. It's no different from Coney Island, Snack Attack, Meteor Melee, etc. Just boring.

While it's pretty much the only button masher in the game alongside Vine Country, that doesn't mean it's any better. It's better than most button mashers because all you do is mash away the body parts of a Pokey, which means you can predict when to take a swift break from constant mashing, if that makes sense. But I still don't really like it.
