Happy Dungeons

Their are so any ways to get this achievement you could play the game without boosting this achievement but for the people who do the easiest way to do so is to complete any level easiest one is level 1 but before you go the last door just wait their for the amount of hours needed best way is to leave it on while your asleep or at work but dont quit you have to go through the door for the hours to count towards the achievement. Happy boosting
