Various people have constructed unusually long and slow rollercoasters in the 1999 video game RollerCoaster Tycoon since its release. The 70-minute long "Mr. Bones Wild Ride" became a popular internet meme after images of it were posted on imageboard 4Chan, and one anonymous user of 8Chan went on to create the longest and slowest possible rollercoasters in 2015. The 210-day long "Kairos — The Slow" reached a large amount of popularity after being posted on Tumblr.

Background
Theme park simulation game RollerCoaster Tycoon allows its players to build a virtual amusement park and design rollercoasters. Kill Screen stated that the game has shown to be "oddly capable of indulging the morbid propensities of its players," as players may kill off the guests of their theme park by dropping them in a lake or making attractions crash deliberately. Another morbid "torture" technique practiced by some players is to, as Eric Limer of Popular Mechanics described: "make a coaster so slow and so long that its passengers would starve to death."

Virtual rollercoasters
A few specific rollercoasters have received media attention after footage of them were posted on imageboards and social media.

"Mr. Bones' Wild Ride"
Built with 30,696 feet of track, "Mr. Bones Wild Ride" was first posted on the imageboard 4Chan in the form of a description and some images. A cart would take 70 minutes of real time to complete one loop, which is represented as four years of "in-game" time. It is unknown whether "Mr. Bones Wild Ride" actually existed as it was described, and its creator has remained anonymous. The rollercoaster has become an internet meme associated with "troll antics."

"The Wheel of Life and Death" and "Kairos — The Slow"
In 2015, a video of a 60-hour long 'vintage car ride' titled "The Wheel of Life and Death" was uploaded to 8Chan. The track supposedly uses up all accessible data slots of the game, making it impossible for the track to be any longer. Its creator initially thought that the rollercoaster was the slowest and longest possible. Chloi Rad of Kill Screen described the track as a "fever dream of interlocking tracks like an eternal pattern in some abstract medieval hell."

Later that year, the same user posted a short video on 8Chan of "Kairos — The Slow", a 'car ride' that takes 210 real-life days to complete. The large spiral-shaped rollercoaster takes 3,000 in-game years to complete because, as its carts leave the station, they immediately slow down to 4 miles per hour. Because the track is completely level, the carts continue moving forward indefinitely, but continuously slow down, its speed tending to zero. The post was shared on Tumblr before it disappeared from the imageboard and became viral.
