A drawing can bend your perception. A game can let you walk through it.
A fourth spatial dimension adds another direction beside left/right, up/down, and forward/back. An impossible drawing combines depth cues that cannot all belong to one ordinary solid. Games explore both ideas, alongside perspective tricks and unusual spatial connections.
An extra direction of space, with three-dimensional views into a mathematically consistent 4D world.
Golf through a fourth spatial dimension.
Courses exist in four spatial dimensions. Rotating the view and changing how the geometry is displayed reveals routes that a normal 3D view conceals. The unfamiliar shapes come from higher-dimensional geometry, rather than deliberately contradictory edges.
Think about moving a ball around an obstacle in a direction that ordinary 3D golf does not offer.
A changing slice of a four-dimensional world.
You see a three-dimensional cross-section of a four-dimensional environment. Turning that slice changes which objects and paths are visible. The design explores feats such as going around a wall along an extra spatial direction.
An object can appear to deform or disappear as the visible cross-section moves, while its full 4D shape stays the same.
In development. The official FAQ currently lists no announced release date and no public demo; checked October 2026.
A physics sandbox for shapes from another dimension.
A fourth-dimensional physics simulation lets you push, stack, and roll objects while seeing a 3D slice. Moving the slice reveals different cross-sections of the same shape. This is an open-ended toy rather than a sequence of puzzle levels.
A tesseract is a consistent four-dimensional object. It can look strange in a 3D slice without being an impossible figure.
Interactive sandbox
Apparent connections, flat pictures, and changing viewpoints alter what you can do.
Impossible architecture becomes a walkable path.
The puzzles turn optical connections into traversable architecture. Rotating a section of the scene can make separated walkways appear to meet; the game then treats the apparent connection as a route. Its impossible stairs and isometric buildings bring the logic of impossible drawings into play.
Follow how a path changes when a platform is rotated into a new viewpoint.
Apparent size becomes physical size.
Forced perspective is the central mechanic: objects held in view retain their apparent size, then become larger or smaller when placed at different distances. Other puzzles turn carefully aligned painted fragments into apparently solid objects.
Compare apparent size on the screen with the object’s actual scale after you set it down.
Photographs open into traversable worlds.
Pictures can be placed into the environment and become physical spaces. A flat image changes the scene around it, making the boundary between representation and world part of the puzzle. This is a rule for transforming 2D images into 3D spaces, rather than a fourth spatial dimension.
Watch which parts of the existing world are replaced when an image is placed.
Rotate a 3D world to change a 2D route.
A two-dimensional character explores a world with a third dimension. Rotating the viewpoint changes which platforms line up in the visible projection. The perspective mechanic makes disconnected structures usable from a different view.
Compare the platforms before and after a quarter-turn: apparent alignment becomes a route.
Looping worlds, surprising connections, and curved geometry change the rules of navigation.
Gravity shifts inside a repeating world.
Changing gravity lets walls become floors. The world wraps and repeats in three dimensions, so falling can bring you back toward another instance of the structure. Chyr describes this geometry in terms of 3D world wrapping; its infinity is a spatial design rule.
Trace a fall through the repeating buildings and notice the relationship between one instance and the next.
A labyrinth that challenges familiar spatial rules.
This first-person puzzle game uses an Escher-inspired world with unexpected connections, changing spaces, and routes that challenge ordinary navigation. Looking, moving, and reconsidering an assumption matter as much as finding a conventional doorway.
Revisit a route and question whether the connection is the one you expected.
Explore genuinely curved geometry.
Its environments use hyperbolic and spherical geometry. These are mathematically coherent spaces with different geometric rules from ordinary flat space. They can feel impossible to navigate, but they do not rely on a contradictory Penrose-style object or a fourth spatial dimension.
Notice how distances, parallel-looking directions, and the amount of space around you behave.
A model and the world around it share a recursive relationship.
A world nested inside a model of itself.
The same environment exists at multiple linked scales. A small model sits inside the world it represents, and moving an object in one scale affects its counterpart elsewhere. Recursive architecture turns a model and its surroundings into a single puzzle system.
Follow the same object across the model and the larger environment.
This guide includes perspective games such as Superliminal, Viewfinder and Monument Valley, unusual spaces in Antichamber and Manifold Garden, recursive worlds in Maquette, and higher-dimensional experiences such as 4D Golf and Miegakure.
No. A fourth spatial dimension adds a mathematically consistent direction beyond ordinary three-dimensional space. An impossible drawing combines depth cues that cannot all describe one ordinary solid.
