What are some creative and fun challenges or minigames that are on Tibia?

Question

In Tibia there are some "puzzles" , "minigames" (world quests) that sometimes makes some quest more challenging or fun , but how many of those are on Tibia? I leave you an example to help you understand what Im asking, for example in the Opticording sphere quest the color puzzle.

Answer 1

I like the Mission 2 of Dreamer's Challenge. It is a surprisingly old quest and you got this interesting minigame to play around matching colors, like a 2D Rubik's Cube! Get more information in this source: Dreamer's Challenge Quest - Tibia Wikio

Answer 2

I am not sure if this will suit your preferences but I would add to the list Stealth Task from A Pirate's Tail Quest since you need to react quite fast along mirrors and guards which requires some real agility skills.

Answer 3

The Cradle of Monsters questline, mission 4.

There are 6 colors of Mutagens and by pulling the levers, you can change the colors in that row or column.  

They change from Black -> Yellow -> Blue -> Purple -> Green -> Red -> Black 

You have 10 minutes to get 11 out of 16 Mutagens the same color. 

If you manage to get all 16 Mutagens as one single color you'll get the achievement Mutagenius.
