Hardest chess gamemode?

Opinions pls

for me its prob bullet

yeah bullet

Bullet definitly

ngl bullet in the lower level is kinda random but higher up its also very hard

Hyperbullet.

30 seconds below is very hard imo.

30 sec is hard on chess.com cause like everytime u make a move it takes longer compared to lichess

True.

umm five minute

5 minutes is just boring for me.
