This is all 15 of the Amazing Feats all 4 players can get when playing minigames.
I'm ranking the difficulties of these Amazing Feats in 5 star difficulty. 1 being very easy and 5 being very hard.
★☆☆☆☆ - Easy to get with just a few attempts.
★★☆☆☆ - Relatively easy, but will take several attempts.
★★★☆☆ - Hard, must have some plan required to get this. Not a lot of RNG.
★★★★☆ - Hard. A mix of skill and RNG.
★★★★★ - Achieved by luck, you must be really lucky.
Balance Busters - Make it to the goal without falling. This one is hard, and it takes everyone to focus. (★★★☆☆)
Consistent Distance - Be the same distance away from the target. It's hard enough to keep the pointer still, no matter how little movement you do or even place it flat on a table. (★★★☆☆)
Dart Domination - Score 100 points or greater without missing a shot. It's ranked one of the easiest because as long as everyone presses A on the same target at the same time, then you all get the points. (★☆☆☆☆)
Drop of Destiny - Drop all 3 tokens and get the same score. When you press A to drop your token, it's down to luck that it goes into where you want it to go. (★★★★☆)
Fleet Footed - Execute 13 perfect jumps and reach the finish line. The timing is pretty tough, but plenty of retries will help get this. (★★★☆☆)
Going the Distance - Reach the same distance, any distance greater than 0. If everyone puts the same amount of force when shaking the Wii Remote, then it should be enough for everyone to reach the same distance. But it's hard. (★★★☆☆)
On a Roll - Reach the finish line at the same time. The logs that head towards you are why this is difficult. Sometimes, the logs that head to you in a certain direction is enough RNG that can make or break this achievement. (★★★★☆)
Perfect Timing - Reach the ground at the same time before the timer runs out. As long as everyone presses A at the same time and does not shake the Wii Remote, it's easy to get. Now, if everyone had to land at exactly 0, it would have been a 4-star difficulty. (★☆☆☆☆)
Ramblin Scramblers - Collect the same amount of apples within the time limit. There's a lot of apples and spikes. It's hard because everyone has to act accordingly. Even getting hit intentionally if you have a lot of apples than everyone else is a good strategy. (★★★☆☆)
Rulers of the Rink - Get a score of 20 or greater. It's relatively easy with a good start from everyone to spin. You don't even need to end with a pose to get this, which makes this pretty easy. (★★☆☆☆)
Saddle Masters - Stay on your horse until the very end. Very hard, but not the top 5 hardest Amazing Feats. The last 5 seconds of the game are too fast that you just have to guess and be lucky that it doesn't fake you out. (★★★★☆)
Safari Standoff - Reach the finish line at the same time. It's hard because of how close everyone must be at the finish line. I came up with an easy strategy that this can be achievable with just one player playing the game. Of course, without a good plan, this is very hard to get. (★★★☆☆)
Sky's the Limit - Fly the same distance, any distance greater than 0. The easiest strategy for this is to wind each side about 14 times so you can at least fly off the ground at the same distance, but that itself is a bit tricky to do. (★★★☆☆)
Survival of the Fittest - Stay on the billiards table until the end. It's very difficult. But not the top 5 hardest Amazing Feats out there, but it's very close. You don't know where the cue ball is going to aim and hit, so the best advice is for everyone to go corner to corner and hope for the best. (★★★★★)
Virtuoso Vaulters - Reach the same distance, any distance greater than 0. This is what I think is the EASIEST Amazing Feat to get. You can easily by yourself with 4 remotes get a distance of 1 or 14 without a lot of planning. Just shake, but not too fast or vigorously, at the peak of your jump. (★☆☆☆☆)
