Some may think mobile games are suited for youngsters or rookie gamers. While some games are made to the riddle, baffle, and leave you swearing before you try again, there are a few rage-quit games that are diabolically engineered to puzzle, baffle, and leave you cursing before you try again. Here is our list of the most difficult smartphone games.

They’re free, but be careful not to smash your phone in a fit of wrath. Don’t be fooled by Syobon’s small game size. The levels are so difficult, and the fatal traps appear so suddenly, that you’ll perish before you realise what’s happened. It’s only natural for the Japanese to create a game that is hard to complete. When the developers came up with Syobon, we had no idea what they were thinking.

Do you recall the game Flappy Bird? The same devs have returned with another rage-quit game, and it does not disappoint. You are in charge of a small monster with copter blades on its head. All you have to do is tap and modify its trajectory as it rises through the air, dodging obstacles and swinging hammers.

So go ahead and play Swing Copters, and let us know what your high score is in the comments. We were perplexed by Dumb Ways To Die (DWTD). We debated whether we should sigh over each character’s adorable cuteness or scream at them for dying so horribly (and instantly) after you miss a specific tap or fail to complete the level before the timer runs out.
