Gameplay
If your dragon was infected, there was a sprite change on your scroll, and the following message would appear on their page: This dragon is infected! Don’t worry, nothing bad will happen. See the event page for more information. Eggs could be infected as well so long as at least one of the breeding parents was carrying the contagion.

This mini-game worked in a similar fashion to the popular Minesweeper game. Official instructions on how to play are listed below- the meter on the home screen showed which side had been gaining the most support, and ultimately the Cure won.

Trivia

 * It is possible to click on a random tile and auto-win the game.
 * Originally, the event banner said that two-headed dragons would also be receiving sub-type specific Undead Dragon sprites.
 * There is a bug on the site currently changing adult Spitfire Dragons on user's scrolls into Thalassa Xenowyrm eggs with a 4th stage crack when they become infected with the contagion.
 * The dragon featured in the game's home screen is a young Red Dragon that has been infected and weakened for a few days.
 * The game's meter was set up such that if no one did anything, spread would naturally win. This mechanism was removed on the final day of the game.
 * This event's banner title originally said "Congation" instead of "Contagion". This was quickly fixed with an image update.
