You'll likely get this achievement during natural play while going through the other achievements, but if you'd like to make progress in the downtime, this method gets me about 10k per day.
It uses a macro, so you're going to need to download a program called TinyTask (https://tinytask.en.uptodown.com/windows
). In the TinyTask settings, turn Continuous Playback on, and change the recording hotkey to Prnt Screen (I had issues getting any others keys to work). Now load up Cosmo Run.
Get to the screen where you see "Play Solo". This is where you're going to start the recording of the macro. Ideally, you want the macro to be as quick as possible, as that will get you points quicker. Here's all you're going to have to do:
1) Press Prnt Screen to start recording
2) Click "Play Solo"
3) Click the left mouse button when the ball reaches the fourth tile, then click again on the fifth tile (this should end the run).
4) When the "Try Again" screen pops up, WAIT ONE FULL SECOND before clicking "Try Again". This is because on occasion, a free gift will appear on this screen, which causes the "Try Again" to take slightly longer to appear. If you don't wait for that one full second, the macro will fail once you get your first gift (probably after 5-10 minutes).
5) When the "Play Solo" screen has fully loaded, hit Prnt Screen to end the recording.
Overall, my macro turned out to be 6 seconds long. Memorize the steps and try to get yours to be around that long as well, for maximum point-getting.
Now, you're only getting 1 point per run, which doesn't sound like much. BUT, whenever you aren't using your computer, load up the game and run the macro (Ctrl+Shift+Alt+P to start/stop it). You'll be getting ~600 points an hour. So, if you leave this macro running while you're sleeping/at work or school/doing something that doesn't involve your computer, you can get this achievement done quite quickly. Let it continue running if you wish to grind for 200k.
