Sylvan Glade (base game)

The glade is inside a big tree on the Crick Cabana lot in Willow Creek.

1. Travel to Crick Cabana and find the large tree on the lot.
2. Interact with it: view it, water it and compliment its leaves. Repeat until new options appear (sources give slightly different counts, so keep going until it changes).
3. The trunk opens. Choose to go inside and a text adventure starts.
4. Pick these options in order: Follow the Sound, Follow Downstream, Enter the Mist, Travel to Glade.

A wrong choice sends your Sim back out, so just try again.

Forgotten Grotto (base game)

The grotto is behind a boarded-up mine entrance in Oasis Springs. There are two entrances: behind Desert Bloom Park, and down the cliff behind the Landgraab mansion.

1. Raise your Sim’s Handiness skill to level 10. Only then can they pull the boards off the entrance.
2. Click the cave entrance and remove the boards.
3. Explore the cave and pick: Take Wide Path, Climb Ladder, Step onto the Ledge, Travel to Grotto.

The grotto is also a fishing spot with rare fish you will not find elsewhere.

Sixam (Get to Work)

Sixam is the alien planet from Get to Work, and you can only reach it with a Wormhole Generator. There are two ways:

• Scientist career: climb the Scientist career until you can invent the Wormhole Generator, then upgrade it at the top of the career and use it to travel to Sixam.
• Rocket: build a rocket ship from Build/Buy, upgrade it with a Wormhole Generator and fly it to Sixam.

To go back later you need the Wormhole Generator again. Look out for geodes: Sixam has its own collectible geodes.

Magic Realm (Realm of Magic)

Travel to Glimmerbrook and walk through the glowing portal into the Magic Realm. Once your Sim is a spellcaster they carry a Glimmerstone, which takes them to the realm without walking to the portal.

Hermit’s House (Outdoor Retreat)

Deep in the Granite Falls forest is a cave hidden by vines and brambles. It is easy to miss: zoom in and pan the camera slowly along the rocks of the national park lot.

1. Click the overgrown entrance to start the text adventure.
2. Pick: Step Forward, Go Through Web, Ignore the Object, Travel Towards the Sim.
3. You come out at the hermit’s cabin, where you can meet and befriend him.

Mt. Komorebi peak (Snowy Escape)

1. Go to Mt. Komorebi in Snowy Escape and use your phone to plan a social event: the mountain-climbing excursion.
2. The climb starts at the onsen bath house. Complete the goals of each stage to move on.
3. The route goes from Base Camp to The Croft Icefall and finally to the summit.
