15 Sadistic Xbox One Achievements Only Hardcore Gamers Unlocked

5. Volleo - Threes!

There's just so much about this achievement that is pure evil. For starters it's worth 99G, which will make the OCD in all gamers go awry when it ruins their even Gamerscore. Then there's unlocking the achievement itself, which requires you to create a 6144 card, which requires an absolutely flawless run to obtain. For those unfamiliar with the game, you start on a 4x4 grid, and have to combine numbers to make larger numbers. Such as 3 to into 3 make 6, then 6 into another 6 to make 12 and so on and so forth all the way to 6144.

Actually getting a 6144 card is so challenging however, gamers have resorted to using computer programs to solve the puzzles for them. And even the best solvers out there only manage to get a 6144 card a fraction of the time. So, if a computer that was designed to do this is having a hard time, there's little hope you'll actually manage to ever unlock it on your own.
