Bullet is for very experienced players to show off their skills. Lots of kids play it anyway.
Blitz gives a little more time especially with an increment and can be useful for testing new openings, but otherwise is probably best left to experts.
Rapid is what most experts say you should focus on. 15/10 gives you time to think and with the increment, end games can be less frantic. Of course it's just a game and if you're playing just for fun, play whatever you want.
Hello!
could someone walk me through the difference between blitz, bullet, and rapid?
And maybe explain how each could benefit the skills of a player? Which should I focus on more? etc
I love the standard and daily play but i never know what to pick within these three categories.
