15 Hardest Video Game Achievements Of 2017 (So Far)

11. Mastering - Chime Sharp

When you first look at Chime Sharp, it makes no sense. You're given a board where you have to use Tetris style pieces to make cubes until the board is covered, and then you win, but even that description doesn't add up, though that's seriously the premise of the game. Take a look for yourself, there's not much to it:

To unlock Mastering, just as the person did above, you need to achieve 500% coverage. What that means is you need to play Standard Mode and get 100% coverage on all 5 levels that you play. You must do this all without failing AND without running out of time, because of course you're being timed.

All this seems easy, but here's something to put it in perspective. According to TrueAchievements (essentially the go-to achievement tracking website for achievement hunters), this achievement is only unlocked by 1 tracked gamer on that site.

Now, keep in mind that's only tracking Xbox, and the video above was from PS4, so we know at least 2 people have managed to do it. Still, that's TWO people among a sea of gamers across two different consoles. Even with that, the achievement is sitting at 0.15% on Xbox Live, which is high considering the absolute rarity of people unlocking it.
