Logo quiz is a game that where players guess the logos of popular brands. It has a really simple concept – erase part of the logos that people are familiar with and let players guess the name of the brand through a partially shown logo. This concept makes players naturally stick on this game because players will think they really know the name of the brand, but it’s on the tip of their tongue (or rather, fingertips)! And when players finally recall the name, it brings a great sense of accomplishment.
Because of the simpleness of its core concept, it is easy to learn playing this game. The more logos players answered, the more levels will be unlocked. It became a really popular game even though the UI is not very exquisite.
It has in-app purchases of hints, game coins etc. But as a quiz-type game ended by “correct answers”, instead of paying money, players can easily google and get those answers because lots of people were discussing it and posting answers.

Presentation feedback:
I wasn’t able to show how to add more masks in the prototype but basically if you want to add more you just click on the circle or square multiple times and it’ll keep adding masks to your camera view so that you can position them and size them however you want.
