It all started in 2021, when on November 9th the first server led by Guffo (originally called "Fancade with Guffo" and then renamed to "Guffo Garden") was created. As the server grew in size, new activities were introduced for the members, including a relatively short series of server events related to Fancade called "GuffoChallenges", more commonly referred to as just "Challenges". These were simple Fancade tasks given to the members, usually about making certain scripts and voxel-arts or reaching highscores in games. In the following period (mostly in the second half of 2021), many modifications happened, which ultimately led to the current version of the GCs. During that time, the transition to the now-archived "Guffo Garden" to the new server called "GuffoChallenges" was being planned out. On 30/10/2022, the new server was officially opened, around the 8th edition of the new series.

After the 12th (and last) edition of the beginning series, the counter was resetted and the new series began. The little Challenges were changing to something bigger: members had to make a game together in collaboration, under a set theme. The event was renamed "Collab Challenges", and it was a very ambituous idea, which lasted for only a couple of editions (up until edition 5b of the new series).

From the following edition on, it was decided to split the members in teams, and have each make their own game. That was still difficult to manage, and so the Collab Challenges changed again soon after: the participants were split again, but in duos, and the time limit was reduced to the current 2 weeks.

With this last alteration (on the 9th edition of the new and current series), the event version closest to the present one can be spotted: the Collab Challenges were over and soon the old name "GuffoChallenges" overtook the others. The GCs kept the 2-week-long time limit, but became solo game-jams. The themes were now put in kits accessible to everyone on Fancade and the task was to make games based on the block given in said kits. The event continued on that very stable format and didn't change a lot.

On 28/09/2023 the server got more community recognition as the roles "FanEvent Coordinator" and "FanEvent Winner" were suggested and then introduced in the Fancade Discord server. Guffo managed to get his coordinator role, and with that the opportunity to write in the newly-opened "fan-events" channel about the GCs, with their themes and results.
