Read in this order
Read the first night before you spend Gems. Use the class guide when you know what killed you. Use the chunk guide when the island needs a boss totem. Use the bones guide only when a recipe is waiting on bones or an artifact and the chest you expected is empty.
Which 100 Days on Chunk guides are published?
First night on the chunk
Equip a class in the lobby, craft the first chunk for 8 wood and 2 leaves, and set up food and a night defense before you spend Gems.
Choose a class and earn Gems
Buy a class in the lobby shop, equip it before the run, and match Chef, Medic, Lumberjack, Ninja, Vampire, or Engineer to the problem that ended your last attempt.
Craft chunks and defend boss totems
Place rarer chunks before you hit the placement limit, then beat Grounder or the Pharaoh and protect the boss totem so the day multiplier applies.
Bones, quarries, and the artifact
Bones are required for the graveyard boss chunk, but quarry chests and legendary deserts have already failed some players. Use the craft prompt, not a guessed drop.
