The GrazAndSeek Challenge Continues!
🎉 The GrazAndSeek Challenge Continues! 🎉
Thanks to your enthusiasm and spirit, the challenge is heating up! Since the first riddle turned out to be quite the brainteaser, we’ve decided to give you all five riddles right away. This way, you'll have more time to crack the codes and climb the leaderboard!
How to Play (Step by Step)
Solve the Gatekeeper Puzzle 🔐
- The one image in the announcement post is the first puzzle. Decode it → get the Gatekeeper QR Code.
Hunt the next 4 QR Codes 🗺️
- Each scan reveals a new riddle.
- The clues get harder—bring a notebook and maybe a UV flashlight 😉
Crack the Final Code 🔣
- Combine the fragments revealed by each QR.
- Locate the hidden number pad (yes, from the Gatekeeper QR Code).
- Enter the 4-digit code, and on success, you’ll be instantly placed on the leaderboard.
Watch the Leaderboard 🏆
- Check out on which place you are on the Leaderboard. Updates will run live at worldmappin.com/GrazAndSeek-Leaderboard

It’s the most important one — you’ll need it to log in and enter your answers into the number pad.Riddles 2, 3, 4, and 5 each reveal one number.

Gracias a su entusiasmo y espíritu, ¡el reto se está poniendo interesante! Como el primer acertijo resultó ser todo un desafío, hemos decidido darles los cinco acertijos de inmediato. Así tendrán más tiempo para descifrar los códigos y escalar posiciones en la tabla de clasificación.
Cómo jugar (paso a paso)
Resuelve el Rompecabezas del Guardián de la Puerta 🔐.
- La imagen de la publicación de anuncio es el primer rompecabezas. Descifrarlo → obtén el Código QR del Guardián de la Puerta.
Caza los siguientes 4 códigos QR 🗺️
- Cada escaneo revela un nuevo acertijo.
- Las pistas son cada vez más difíciles: trae un cuaderno y quizá una linterna ultravioleta 😉.
Descifra el código final 🔣
- Combina los fragmentos revelados por cada QR.
- Localiza el teclado numérico oculto (sí, del código QR del Guardián de la Puerta).
- Introduce el código de 4 dígitos y, si lo consigues, entrarás instantáneamente en la tabla de clasificación.

The chocolate was yummy 😋
I wish fun to everyone while solving the riddle 👏🥳
This was a very interesting quest 🙂
I racked my brain until I realized that the next step required that chocolate😃
Great thing you didn´t give up! 😀
Hooray!
First online 😀
Congrats!
Thanks 🙂
Congratulations to you too.
You are the first to discover the solution.
👏👏👏 yay!
😀
Well done @duskobgd
Thanks :-)
😎😘👍
No wonder the flip!! I didn't see that 😅
😂
Last time you had a contest I won something but because I was travelling and could not immediately reply you disqualified me.
Ironic for a travel based community.
Yeah, that was very unfortunate. We thought it was enough to announce that before in multiple posts, several times that you have to react within 24 hours when being picked that day... but we learned from it 👍 Maybe this time you are luckier if you solve the riddle.
Finally managed to be the second online :) It was a nice engagement and a new learning for me.
😎😘👍
Hahaha amazing that this goes on... btw, I didn't know that you spoke so well spanish hehehehe 🤣😇
Jokes a side, man I am so happy that we got to connect more on this meeting, now I picture more of the story of your persona and I am so happy to have met you, you are an amazing person!
Looking forward to keeping up with your stories and meeting anytime soon!
Hey hey deja de darle vueltas y completa el retoooooooo 🤣
