Funny story for the non spanish-speakers about the name.
"Game Jam" is usually called "Game JamOn" in Spain, which are 3 words: "Game, Jam and On", because in spanish "JamOn" means "ham" in english.
When we first thought about the 2018 game jam, I asked "what is the meaning of 'jam'" (because i didn't remember at the time), someone said "jamón" (ham), nobody corrected that person, we thought that a ham would be funny in the logo and we chose that name.
Weeks later I realised, not only that "jamon" in english was not "jam" but "Ham", but that in Spain people usually call the game jams "game jam-on"! A funny name I thought original was not only but another name to the list of endless game jams called "jam-on" XDD
