"I am not sure that I've ever seen a more compelling 'show-don't-tell' educational tool than 4D Toys." –Ars Technica

What if you received a box filled with mysterious toys from a fourth spatial dimension?

• Playfully explore and marvel at beautiful shapes powered by a groundbreaking 4D+time physics system.
• Poke, throw, roll and watch as they disappear into a dimension you can't see.
• Get an intuitive feel for how four-dimensional objects behave:
• Become a child of the fourth dimension.

In this case the 4D is not time but a 4th dimension of space that works just like the first three dimensions we are familiar with. If you count time these toys are 5D. It turns out that the rules of how objects bounce, slide and roll around can be generalized to higher dimensions, and this unique toy lets you experience what that would look like.

• Over 130 beautiful interactive scenes to play with, with more to be added in updates.

• Groundbreaking 4D+Time Physics Engine that uses new mathematics created for this project.

• Multi-touch & Accelerometer support for rich interactivity.

• 2D/3D "Flatland" Interactive 10 Page Book/Explanation that teaches by analogy about a fourth spatial dimension.

Some things to do:

• Manage to fit the hypercube into the hyperhole!
• Use the 4D shapes as fancy, perfectly symmetric, fair dice that have 5, 8, 16, 24, or even 120 and 600 sides!
• Unbind Rings using the fourth dimension!
• Make a stack of 4D hypercubes and smash it!
• Set up an interesting path for a few 4D dominoes!
• Make levers that throw hypercubes into the fourth dimension!
• Use multitouch to "squeeze" out objects into the fourth dimension!
• Play in a 4D ball pit!
• See Tesseracts (i.e. 4D hypercubes) slide down slopes!
• etc...!

Very Fun!


This app is super cool and I can only imagine how much cooler it would be in VR! My one suggestion is seeing as how two finger rotation rotates around the XY-plane and three finger rotation rotates around the XZ-plane, maybe four finger rotation can rotate around the WX-plane? It would also be cool if three finger drag moved the object along the WX-plane, although seeing as how you can do something similar with dragging both the slicer bar and the object at the same time that isn't as big of a deal imo.



This is one of the best games I have ever played! The visuals are neat, I like the concept, and I find it very interesting how there is an interactive explanation about how the 4th dimension is viewed and why! It was also fun playing around with all the toys that came with it, and I fell it was very worth the money! Good job development team!

UPDATE: Amazing Concept. Excellent Dev Team


When I first bought this app, it kept crashing on the title screen. I told the devs about it with a review and they were VERY quick to respond and fix the problem. 10/10 app. 10/10 communication on their part.
