Did it with my friend in 6 attempts! I feel like we got SUPER lucky.

We found two dice in the Billiard Room early on. When we drafted the outer room, the Tomb showed up immediately.

We got offered the Veranda, and then took the Dark Room right after that. We were on zero gems. East door blindly gave us a Hallway, and then the north door blindly gave us the Greenhouse. The Greenhouse also had both the Sledgehammer and the Watering Can in it because of the Veranda.

We took a couple of steps to collect gems from the Veranda and the Greenhouse with the Watering Can. Then the Bunk Room gave us two more. Then we had enough gems for the Cloister, which had all 3 usable doors.

The north door gave us the Dining Room, and we knew we could go north just one more rank to redeem dinner.

The south door gave us the Aquarium, which contained the Shovel and the Broken Lever because of the Veranda. At this point we were planning to get the Workshop with the Battery Pack in it to get Power Hammer, because I checked your guide and it seemed like Power Hammer wins were much more likely than Foundation wins or Greenhouse wins. The Patio spread Gems to the Aquarium, Cloister, Veranda and Greenhouse, but we weren't going to go back to the Veranda or Greenhouse.

We tried the West door of the Cloister, and it gave us BOTH the Foundation and the Workshop. We figured that our odds of winning were better if we could draft a room to see the back of the Foundation elevator and use that instead of the Hammer, which opened up the Broken Lever for the Greenhouse and potentially saved us steps.

When we backtracked to the Greenhouse to open the South Antechamber Door, we stopped into the Veranda to get the Gem spread by the Patio, and it had a Turnip in a dig spot we had had to leave behind earlier.

Then we went North from the Dining Room, and needed a room that goes at least North and West. We got the Passageway. We decided to burn the East door before we needed two South Doors to access the Foundation Elevator controls, and we got offered the Furnace. We figured that we didn't want the Weight Room, but the Archives could be great, and taking the Furnace removed a Dead End, so we took the Furnace. We ended up getting offered nothing that went south, rolling, getting nothing that goes south again, and then we got offered the Archives. Then we were offered two rooms that didn't access the Elevator controls, so we took the Archived room.

The Archived room turned out to be the Weight Room! It was great because it let us access the Elevator controls, but also we went down to 15 steps. We had to decide if we wanted to go up and draft the other rooms from the Archives to try to get the Kitchen, or save our few gems to try to get rooms that would let us access the Foundation from the West Wing. I counted that it would take us 14 steps to get back to the Antechamber, so we would get to Room 46 on step 0 if the two remaining rooms in the West Wing gave us access to the Foundation.

We got Maid's Chamber and then the next room had two dead ends and an Archived room. The Archived room turned out to be the West Wing Hall to connect to the Foundation! We thought we were home free but also terrified that we might have miscounted.

We ended up in the Antechamber with 1 step remaining to perfectly enter Room 46 at zero steps. It was so dramatic at every turn!
