The two picture scrolls (emakis) on the door are for the self-reset of the room, as well as for giving hints if necessary. The first figure here shows the 'picture' for giving players hints in the task. By matching tea leaf figures to their corresponding number, then translating them into alphabets, players will find out the the cryptic message says "rearrange room".

This figure shows the inside of the scroll - there are actually two pictures in each scroll! For the first picture scroll: There are two different room arrangements that the teams could be replicating, so that no manual reset is necessary (teams would be moving the jars back and forth)!

This is also how the hint would be given to the teams. The second picture scroll would, by default, shows a landscape picture. However, when the system senses that team hasn't been making any progess, it would unroll the cryptic hint to help the team!
