Slots-o-Fun is a colorful bank of slot machines located below the elevators, to the right of the main game room. There are five differently colored rows of five slot machines. Each slot machine is labeled with a different country and has a 4x4 grid of of images with arrows for each row, column, and both diagonals. Activating the "secret state" caused the reels in the slots to change from regular slot machine icons into emoji.
Players were directed that they could enter the secret state by selecting both diagonals and the rightmost column.
The states of the machines are preserved and shared between all players on the team, so everyone should see the same state for each machine. Clicking the spin button will cause the set of displayed images to randomly change to another set.
