together as a group to add a graphic from that community to place. Place was closed on April 3, 2017, at 1:00 PM GMT having been active for a full three days. For April Fools' Day 2018, an experiment launched on the subreddit r/circleoftrust. Upon clicking a button, each user was given one "circle" that they could entrust to others with the circle's password key to unlock and join the circle. While each user received one personal circle, they could join or betray any other user circles. Clicking the "join" button on another's circle would cause the owner's circle to grow bigger, while the "betray" button would cause the owner's circle to no longer function (having "betrayed" the owner's trust). On the r/circleoftrust subreddit, all users have a "flair" next to their username that displays the number of users who've joined their personal circle, followed by the number of other circles the user has joined. Those who had betrayed another user's circle have a null sign ("∅") next to their numbered flair. The experiment ended on April 6, 2018. For April Fools' Day 2019, a social experiment subreddit called r/sequence was released. The experiment consisted of a community-driven sequencer that users interacted with by submitting GIFs or text slides to be compiled into a movie. The order of the GIFs and text slides were chosen by users through upvoting one GIF or text slide per scene. The most upvoted GIF or text slide was locked into the next available scene for every three minutes. At the end, once the entire sequence was filled, it was posted as a full story in an external page. The experiment ended at April 3, 2019, 11:08 PM GMT. For April Fools' Day 2020, r/imposter was released. Users were to identify a machine-generated response from a group of responses to the question "What makes you human?" (and, later, "What makes you an imposter?") and had an option to respond to the question after doing so. The experiment ended on April 3, 2020. For April Fools' Day 2021, Reddit released r/second, in which users have to guess the second most popular option out of a group of three options. The event ended after 2000 one-minute rounds, with the final round lasting one hour. For April Fools' Day 2022, Reddit once again featured r/place, similar to the event featured in 2017. The subreddit featured a 1000 x
