I am a big fan of original tetris, tetris friends But the most I'm interested in is TGM3, there's videos that you might have seen such as "tetris god", "tetris shirase" in tgm3 theres 4 modes and 2 rules "classic rule" "world rule" and "easy mode" "Sakura mode" "master mode" "shirase mode"
Easy mode: self-explanatory, lvl 200 max.
Sakura mode: clear lines with these circles in them. 20+10 stages
Master mode: harder mode, lvl 999 max, max rank: GM
Shirase mode: sudden mode, lvl 1300 max, max rank: S13
Tgm3 is a big challenge even to get gm on a promotional exam, it might take months, or even years to get it, screenshot your best scores, mine is 380 (5 months of only playing tetris friends and TOP, so not really good at tgm)
