conundrum

Strategy
The difficulty the mini-game the Conundrum gives can vairy quite a lot, due to the fact sometimes the mask will be very similar to the rest.

I recommend simply looking straight ahead not moving your camera much to let the masks pass by on your screen, and scanning each row to see if you can see a difference as each mask passes by. Focus on their colors first. If you can't find a difference, move your camera to be able to see the masks faces if you not able to see the bottom rows face. Mechanics
Once the first door is opened, a spawn timer will appear in the top right of every players screen with the Overseer next to it. The timer ranges from 2-3 minutes, and upon reaching zero, the Conundrum will make its appearance close to you. The Conundrum will follow you wherever you move. Once the Conundrum appears, it will give a small explanation on how it's game works. When the Conundrum finishes talking, the Overseer will appear on your screen and countdown from 3, then laugh and fly off your screen, to which then the mini-game begins.

There will be three horizontal rows of theater masks spinning around each player. One mask will be different from the rest of the bunch. This mask can be very different, color and facial expressions being visibly different from the rest, or sometimes the mask is only a shade darker then the rest. There will be 3 rounds, and a timer will appear at your cursor, lasting around 12 seconds. If the timer runs out then you lose. The goal is to find the odd mask before the timer runs out. The timer will reset once you find a mask.

Every time the Conundrum spawns, their difficulty will increase. The color of the fake mask will become simply a darker shade, or even the exact same color. The fake mask face will sometimes be the exact same as the other real masks. Eventually the only difference will be the fake masks eyes, staring into your soul. Extra rounds also start getting on, so far up to 4 rounds.

{{char}} Conundrum appears as a clown jester; his head has four different colored masks with varied expressions, which he rotates from time to time. He is accompanied by apparently another separate entity, a 2D black figure with a single white eye, who always carries a pocket watch.
