الوصف
Wanted to upload this with a bit of editing to show what is going on. Note that those requirements are how I understand them, and we're not 100% sure on them due to no one reverse engineering the requirements in this patch yet.
The way the grade works is that you get a point for each completed section where you cleared 6 or more tetrises, with the first section spanning levels 0-199 and the rest being chunks of 100 levels. The final point is awarded when you clear the mode, if you had more than about 60 tetrises (we know 63 is enough for this). This makes up the top number of the grade, while the bottom number goes up every 111 levels, up to Nine for reaching the end, and you get upgraded to Ten for surviving the end credits.
So in summary, to get Ten of Ten, you need to survive the whole ordeal, clear 60+ tetrises total, and make sure every 100-level section contains at elast 6 tetrises.
