Cracked Minecraft is simply an unofficial copy. Players using versions of "Cracked Minecraft" must instead play on special "Cracked Minecraft Servers." These servers are specifically designed to bypass Minecraft account security checks and allow players to join even without having a legitimate Minecraft account.
Cracked Minecraft allows everyone to play one of the best-selling games of all time! However, Cracked Minecraft is illegal and will only be able to play on Cracked Servers.
