Insight

gets pretty hard! but surprisingly fun. One of the better times I've had with one of these "rule discovery" type puzzle games.

This game is in the same vein as Understand, and to some extent other rule discovery puzzles like The Witness, Taiji, LOK Digital, and more. And I think it does its job very well. I think the symbols are pretty clear; they are a puzzle to understand, but they make sense once you get the insight and learn how they behave.
The game is also very straight to the point: simple graphics, no embellishments like exploring a world or some sort of story. Just the puzzles. Which is always nice when you just want the puzzles.
With a low price point, this is an easy recommend if you want to play rule discovery puzzles.

该游戏是 Understand 的精神续作，玩家需要猜出 49 种不同的机制，但是机制之间又有着一定的联系，部分关卡的机制过于神秘了，后面的纸笔部分也有着一定的难度，但是猜出规则的一瞬还是很爽的！
The game is like "Understand 2", the player needs to guess 49 different mechanics. Some mechanics in the game is too confusing, but can you infer them from former experiences. The continuous "Aha-Moment" really makes me overjoyed.

A few mechanics I found really obscure, but the hint discussion thread was enough help to get unstuck. Overall though I could have the promised Insights on what to do, and on how to do it, given some time and taking some breaks. Recommended if you played games like Undertstand (which is the most similar), the Witness or Taiji and enjoyed what they do with rule discovery.
