4Dice vs 4D Toys
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
4Dice
Explore a hypercube visualized as a 4-dimensional, 8-sided die. Interact with the die using multitouch controls to reveal its hidden faces as they come into view during rolls. Experience a unique perspective on geometric visualization.
- Multitouch controls
- 4D hypercube exploration
- Interactive die rolling
- Geometric visualization
- Unique perspective rendering

This application exploits multitouch controls to explore a hypercube labeled as a 4-dimensional, 8-sided die. The hypercube's eight cube-shaped faces are rendered as a 4D being would see them in 4D light: thus, only one, two, three, or four cubic faces can appear at one time while the die rolls, but no more. Faces that would be invisible to a 4D gambler cannot be seen without interactively rolling the die to bring them into view.
4D Toys
Explore and interact with mind-bending 4D physics objects. This app offers a playful and educational experience, allowing users to discover how four-dimensional objects behave through intuitive interactions and a unique physics engine. It's designed to provide a tangible feel for abstract spatial concepts.
- Groundbreaking 4D+Time Physics Engine
- Over 130 interactive scenes
- 2D/3D 'Flatland' explanation book
- Anti-Gravity and Wireframe Projection
- Export meshes for 3D printing
- Play with hypercubes and hyperholes

"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. Features: • 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. • Special buttons: Anti-Gravity, Wireframe Projection, 4D Accelerometer and ability to export meshes for 3D printing. 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...!

Verdict
The clearest difference is price: 4Dice at Free against 4D Toys's $6.99. 4Dice also leads on review sentiment (100% vs 91%). 4D Toys's advantage is ratings volume (705 vs 4) and update cadence (every 4 months vs every 18 months). On rating, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
4Dice is free to download; 4D Toys costs $6.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.8 for 4Dice against 4.8 for 4D Toys. That said, the two scores are not equally well evidenced: 4D Toys has 705 ratings behind it against 4, so its average is the more settled of the two. Written reviews are what separate them: 100% of 4Dice's written reviews are positive against 91% of 4D Toys's.
4Dice ships an update every 18 months, 4D Toys every 4 months. The most recent releases landed on October 23, 2026 and November 1, 2026 respectively.
