Understand is an experimental puzzle game about guessing rules. In each level, you have to figure out the rules through trial and error, then draw a line satisfying all rules.
In each level, you draw a continuous line across a grid, aiming to satisfy a set of hidden rules. The game provides feedback on which rules your line fulfills, but never outright states what those rules are. This forces you to engage in a process of trial-and-error, forming hypotheses, testing them, and refining your understanding until you uncover the complete ruleset.
Just as you think you've gotten the hang of a particular mechanic, the game throws you a curveball. Reviewers highlight how "Understand" subverts expectations, presenting puzzles that don't conform to the patterns established in previous levels. These "out-of-the-box" challenges compel you to approach the problem from a fresh perspective, shattering your preconceptions and forcing you to rethink your strategy.
As you venture deeper into the game, you'll notice a palpable sense of progression in your problem-solving abilities. The early levels serve as effective tutorials, teaching you the core skills needed to tackle the more complex and demanding challenges that follow. Reviewers describe a growing confidence as they piece together the larger picture, overcoming obstacles that once seemed insurmountable. The satisfaction of cracking a difficult ruleset and applying that knowledge to subsequent puzzles is consistently praised as a key part of the gameplay experience.
