Because free realms keep updating so must the guides to the adventure coins.
First is Snowhill Rare Exploration: Penguin Point.
Without trying too hard to follow the guide. There is an easier way (Thanks to updates). Teleport to Wintery Basin. Jump over the fishing supplies and head north.
Snowhill Rare Exploration: Beyond the Springs
Free realms made an update changing the position of the token. It is now behind the springs. Enter the springs go right and it is on the path left of Carrie.
Merry Vale Elite Exploration: Party Tent
Not much of an update but on the guide it says the Midway is on the northwest. This Midway is on the northeast.
