Baffle Boards

are a mechanic introducted in Yo-kai Watch 2. Scattered around the game world there are hidden boards that must be revealed using the Yo-kai Lens.

Once the board is checked, the player must guess the name of a certain Yo-kai, after being given three clues. After correctly inputting the Yo-kai's name, the Baffle Board will create a and become permanently visible without having to re-scan it.

The player must then befriend the Yo-kai if they haven't already, and summon them onto the Yo-kai Circle. The player must currently posess the required medal to summon the Yo-kai—if they were previously added to the Medallium and then traded away, it won't work. However, the medal is no longer required after summoning the Yo-kai, so temporary trades with friends to unlock the Yo-kai Circles are possible.

The summoned Yo-kai will then give the player access to a special feature or cause something to happen to the surroundings.
