I grinded for this goal for weeks--starting pretty much right after getting the regular GM--and then everything came together. Then it came together again.

This is a way harder goal than just getting Grandmaster in this game; the 20G code makes it so that the game _starts_ you on the maximum speed that normally doesn't kick in until level 500.

It's a similar difficulty jump between getting a maxout in NES Tetris and getting a level 19 start maxout, although getting any grandmaster grade in this game is easier than a maxout.

The challenge of this mode is that not only do you have to survive 999 levels at the maximum speed, you also still have to hit ALL the score and time requirements (listed in the bottom right). This requires stacking ridiculously clean and smart and going for dirty tetrises rather than just waiting for a dig to come together. Combos can also really help juice the score. If you spend too long digging/cleaning up in the first half, you're pretty much guaranteed to miss the requirements, and 20G makes it really difficult to make the stack go _down_ because of the limited placement options. So it's a tightrope.

One cool moment was 11:28. Getting that bar over required rotating and shifting on exactly the same frame. It's called a synchro. Was proud of this one.

I played this back on Feb 25, jsyk.
