I still have a joker up my sleeve! The Joker occurs in various games and can replace any card. Usually a court jester is pictured, hiding his face behind a mask.
The joker emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the activities
category. Because the joker emoji has been around for quite some time, it should display correctly in the majority of operating systems.
