Flappy Bird is arguably the most difficult video game ever made. It's so challenging that players vent their frustrations on Twitter with the hashtag #flappybirdproblemsnight.
That said, perhaps you're done with Flappy Bird and crave an even greater challenge. Well, the following mobile games are just as tough and perhaps tougher than Flappy Bird, despite playing differently. You've been warned.
Super Hexagon
Guide a triangle through a constantly moving hexagon. Good luck lasting more than 30 seconds.
Super Ball Juggling
Despite posting tips for this game, some of us still don't have the hang of it. The idea is to bounce two soccer balls between two characters without messing up once.
Ironpants
You'll probably delete this one minutes after downloading it. It's ridiculously unfair. You must tap to keep a superhero in midair as he flies between crates, but the unforgiving controls make this obstacle course almost unplayable. We currently have a score of one. One!
Shuriken Block
Tap ninja stars before they strike the characters at the bottom of the screen. Somewhat easy at first, then super intense moments later.
Ghosts 'N Goblins Gold Knights
Who would have thought a Ghosts 'N Goblins game would be the easiest of the list? This sequel to the beloved classic puts you in control of heroic knight Arthur as he attempts to survive the Ghoul Realm. Cheap enemies and deaths? Check and check. Not like Flappy Bird from a design standpoint, but difficult all the same.
