Game Guide
MyRin uses five distinct puzzle types, each requiring a different mental approach. Knowing which type you're facing is half the battle.
One of the most common frustrations in MyRin is applying the wrong mental strategy to a puzzle. A sequence puzzle and a spatial puzzle are both "logic puzzles," but they require fundamentally different approaches. Using a sequence-solving approach on a spatial puzzle doesn't just fail to help - it actively blocks the solution by leading your thinking in the wrong direction.
Here's a breakdown of each puzzle type you'll encounter in MyRin and the mental approach each one calls for.
Sequence puzzles present a pattern across a series of elements and ask you to identify what comes next, what's missing, or what the underlying rule is.
What they're training: Inductive reasoning - the ability to derive a general rule from specific examples.
The right approach: Look at the differences between elements, not the elements themselves. The rule is almost always encoded in the transition (what changes, and how), not in any single piece. If you're looking at individual elements and finding no pattern, shift your gaze to the gaps between them.
Common mistake: Trying to memorize or recognize each element individually instead of extracting the transformation rule.
Spatial puzzles involve mentally rotating, flipping, or reconstructing shapes. You're asked to see how pieces relate in space - what fits where, what a shape looks like from a different angle, or whether two representations are of the same object.
What they're training: Visuospatial reasoning - one of the most broadly transferable cognitive skills, strongly correlated with mathematical and scientific reasoning.
The right approach: Don't try to mentally simulate the entire transformation at once. Anchor one feature - a corner, an edge, a distinctive mark - and track only that feature through the transformation. The rest usually follows.
Common mistake: Trying to hold the entire shape in working memory rather than using a single reference point as an anchor.
These are the classic constraint-satisfaction puzzles: given a set of rules and relationships, determine the only arrangement that satisfies all of them simultaneously.
What they're training: Deductive reasoning and inhibitory control - suppressing plausible-but-wrong solutions to find the one that's necessarily true.
The right approach: Work from the most constrained element (the one with the fewest valid positions). Don't try to solve everything at once - make one forced deduction, update your mental model, then look for the next forced deduction. Chain them.
Common mistake: Trying to hold all possibilities in working memory simultaneously instead of eliminating one at a time.
Pattern completion puzzles show you a matrix or grid with a missing piece and ask you to identify which option correctly fills the gap.
What they're training: Abstract pattern recognition - identifying rules that operate at a level above the surface features of the individual elements.
The right approach: Look for rules operating across rows AND columns simultaneously. Many pattern completion puzzles have two overlapping rules - one governing horizontal relationships and one governing vertical ones. The missing piece must satisfy both.
Common mistake: Identifying a rule in one direction and assuming the correct answer. The answer must be consistent with all rules in all directions.
These puzzles require you to hold and manipulate information across multiple steps - tracking what changed, what was moved, or what state the puzzle was in at an earlier point.
What they're training: Working memory updating and executive function - the cognitive controls that manage attention and mental resources.
The right approach: Narrate your reasoning out loud or in writing. Working memory challenges fail not because players don't understand the rules but because they lose track of state. Externalizing the state - even writing it on a piece of paper - removes the cognitive load of tracking it mentally.
Common mistake: Trying to keep everything in your head. This is the one puzzle type where using scratch paper is not cheating; it's the intended approach.
From level 60 onward, MyRin regularly presents puzzles that blend two or more of these types - a sequence puzzle with a spatial component, or a logical deduction puzzle that also requires working memory to track a multi-step solution.
The key to handling these is to identify each component separately before trying to solve the combination. Ask: "What type is the core of this puzzle? What secondary type does it involve?" Solve the core first, then bring in the secondary constraint.
