Party Panic

This will take 17+ hours due to the rounds lasting 45 seconds + results/loading screens, but can be done solo.

Going for this achievement, you will get most of the other minigame-related achievements(score, wins, games played).

1. At the main menu go to Online - Host for Friends
- The achievement tracker doesn't seem to go up in local custom party, only in minigame with random gamemodes.

2. Select game mode: Custom Party, First to: 10 000 points, bots & dancing OFF
- This will guarantee you 1 million points and 100 wins after 100 games played. No bots= no competition!

3. Toggle all gamemodes OFF, then go to Totem Brawl and toggle it ON and press "Apply Changes"
- In this gamemode, all you need to do is to walk to the totem, then wait for the timer to run out.
- The totem generates 1000 points over 20 seconds, so be sure to pick it up before the timer is at 20.

4. Start the game by selecting "Ready", then hold . Pick up the Totem, wait out the timer, hold after receiving your score on the result screen. Repeat for 10 rounds until you get 10 000 points.

5. Repeat step 2, press "Apply Changes"( gamemode is saved from previous game), then repeat step 4.

After 100 games, with a total of 1000 rounds, you will finally have 1 million points!

The easiest way to get this achievement out of the way is in Custom Party. It's still a bit of a grind but this will be much easier. You can set this up to get 100 wins, 100 games played and accumulating 1,000,000 points.

To set this up and earn this the fastest you will need 4 controllers and you want to sign 3 of them in as guests. From there when you get in the game you can Start the Party!

Put the settings to the following then accept:
Game Mode: Custom Party
First to: 5,000
Bots: Off
Dancing Game: Off

On the next screen toggle all the game modes off. Then go through all the game modes and manually turn Plinko Panic on and apply changes.

With Plinko you can move your 4 characters to each section where the balls drop and just let them stand there for each round. All the points your guest controllers earn count for you. So when the match is over no matter which person wins you get credit for a win on your main account and all the points. You can adjust the points needed to win as you go to make it align with your 100 games. If it looks like you're going to need less you can lower it for a few matches. If it looks like your going to need more then raise it. Still a bit of a grind but a heck of a lot faster than the other methods.
