Each world & difficulty has a bonus location that only opens up after you earn 3 skulls on each level. These special locations provide great rewards and therefore once you complete them they are locked for a set amount of time before you can play them again.
|World||Bonus Location||Countdown Starts At|
|Ailing Kingdom||Blessed Garden||24 hours|
|Kingdom of the Sands||Goddess of Destruction||24 hours|
|Battlefield||Endless Rain||48 hours|
|Underworld||Light Bringer||48 hours|
TIP: Play your bonus locations when they become available to start the next countdown timer as soon as possible.
