Saint Georgeโ€™s interactive story:

The Whatsapp bot that become viral on 23 April (27.325 users)


In Catalonia (Spain), Saint Gerorgeโ€™s day is one of the most original celebrations, book and flower stalls are set up along the streets of Barcelona ๐ŸŒน๐Ÿ“š

So I created a gamechat that explains the Saint Georgeโ€™s story from the point of view of one the characters (๐Ÿฎ๐Ÿ‘ธ๐Ÿผ๐Ÿคด๐Ÿ‘‘๐Ÿ‘จโ€๐ŸŒพ๐Ÿฒ), in order to advance the users have to interact with other participants and find the next character that unlock his story.

Letโ€™s see an example:

(Note that all the texts are in Catalan)

As you can see, to start the history you must start a conversation with the bot and text the keyword: conte.

Then, the bot explain the introduction of the story and assigns you a character (in this case the princess ๐Ÿ‘ธ๐Ÿผ). To continue, the user need to find another participant with the king ๐Ÿ‘‘ character and attach the contact:

Finally, to end the story, the princess must find the dragon ๐Ÿฒ



I developed the Whatsapp bot using the following elements:

Issues during the event

I noticed several scalability problems when handling requests from more than 10k users. The first hours the new users income where 2/hour (basically my family and friends), then it started growing exponentially until 1000 new users per hour.

At this point the system collapsed and the response time raised to 5 minutes in some cases, that delay stopped the exponentially growing curve :(


I would like to thank my family and friends who trusted in my idea and forward the Whatsapp bot contact.
