Boring or fun is quite subjective while talking about gaming. However, by applying proper design principles, we can put most players in an intended experience even for a very simple game. This article will demonstrate some tricks to achieve that. Video tutorial is at the end of the post.
What is the game 🤔
It is the number guessing game (guessing genre). Its mechanic is simple. A player will keep guessing a secret number generated by the game until it is correct. The game will give simple hint each wrong guess, for example, “Too big” or “too small“. You can try the game provided below.

PISS OFF PLAYERS WITH Feedback elements 😠
Many cases, the feedback mechanism is stressful. Under the time pressure and intense moment, any disturbing factors can destroy players’ concentration. Of course, the purpose of this is to make the game more challenging, not really for pissing off players.
