How to get this trophy:
Step 1: Go into singleplayer -> challenge -> tiny puyo.
Step 2: Select any character you want (doesn’t really matter who).
Step 3: In the handicap settings before the game starts, change the handicap to Sweet.
Step 3.5 (optional): Pick a BGM from the game that you like under the options menu, because you’re probably gonna be hearing it for a while.
Step 3.8 (optional): Mute SFX in the menu if you aren’t keen on hearing the same voice clips come out of whatever character you picked for hour, also recommended so you can listen to the game music without noise.
Step 4: Press play and then tape or otherwise hold your controllers left stick down and to the left.
Step 5: Be prepared to wait a long time to pop enough puyos for this trophy to unlock.
Step 6: When you’ve reached the desired number of Puyos Cleared / you wanna stop grinding, release the stick and intentionally top out.
Warning:
YOU MUST TOP OUT WHEN YOU’RE DONE GRINDING AND IT MUST SHOW THE UPDATING RECORDS / GAME OVER SCREEN. THIS TROPHY ONLY COUNTS PUYOS FOR COMPLETED GAMES, MEANING THAT EXITING WILL CAUSE YOUR STATS NOT TO BE AFFECTED BY THE GRINDING SESSION.
Don’t worry about dying with this setup either, it’s a near statistical impossibility since there’s a way bigger play field, and even throwing puyos off to the side will cause them to pop because of this fact. This is also why 3 color is important, because without 3 color, you risk running into a sequence of pieces that throwing off to the side will not sufficiently clear.
Also bear in mind that while this method may seem slow at first because of the low drop speed, it will gradually speed up as more puyos are cleared, leading to more puyos cleared at a faster rate. I’ve found that in my experience, at around 800-900 puyos cleared, they pretty much start dropping near instantly and the pairs are effectively hitting the ground / other puyo instantly.
Anyway, I hope this guide helped you out! I’m sorry that this method is mind numbing as all hell, but this is the only consistent method to grind puyos cleared short of just playing the game more; which if you wanna do that and be efficient with your grinding, I’d recommend playing lots of endless Fever, you can even kill two birds with one stone and unlock the screen cleaner trophy (it’s pretty easy to get all clears in endless fever) if you don’t already have it. Either way, I wish you luck with this trophy, it will take roughly 8-10 hours real time if you’re starting fresh, or if you’re starting from the previous trophy (50,000x puyo clears), it should only take around 2-3 hours. Not exact numbers but it should be fairly close to the result.
