Happy Birthday, Erno Rubik! In celebration of this great innovator's contribution to the world of puzzles and toys, we present some of the most interesting and 'fun' takes on his classic Rubik's Cube.
The following are far from exhaustive and are in no particular order.
A very brief history of the Rubik's Cube
The Rubik's Cube was first invented in 1974 (and patented in 1975) and has come to be one of the world's most popular puzzle games of all time.
Erno Rubik is a Budapest born Professor who devised the cube as a means of helping his students understand the concept of three-dimensional problems.
When he devised his twisty-turny robust and colorful device, he had no idea just how popular it would come to be.
1. The Pentamix is Probably the Hardest take on Erno Rubik's Cube
The Pentamix is certainly a sight to behold. It is widely considered to be one of, if not the, hardest Rubik's cube to solve. For many, the traditional cube is hard enough, but this take on Erno Rubik's classic is enough to scare even the most tempered Rubik's Cube enthusiast.
All told, it is made from 975 individual parts and over 1,200 stickers. It was designed by Jason Smith and took about 75 hours to build. As for solving it - that might take considerably longer indeed.
2. The Mirror Cube Puzzle Is One of the Most Unique Takes on Erno Rubik's Original
This Rubik's Cube 2.0 of sorts lacks any colored stickers but consists of various pieces of different sizes. Although it sounds simple enough a quick glance at the uncompleted state should be enough to perplex any Rubik's Cube veteran.
3. The Quadruple Cube Is Certainly an Interesting Take on the Classic
The Quadruple Cube is one of the more unique modifications on the traditional Rubik's Cube. It is, in effect, four mini-cubes in one and one that is certainly a fun alternative to one of the best-loved puzzles of all time.
Not only is this cube a challenge, it is also aesthetically intriguing.
4. The Gearball Brainteaser is Possibly the Hardest Take on the Rubik's Cube
The Gearball Brainteaser is one of the most beautiful and complex forms of the Rubik's Cube around. If you think the original cube was hard you should try this magnificent beast of a puzzle.
Not only that but you can watch the gears turn as you try to solve it. Satisfying and challenging all at the same time.
5. The Megaminx Speed Cube is Something to Behold Indeed
The Megaminx Speed Cube takes the concept of the standard 2 by 2 or 3 by 3 cube and throws it in the bin. It looks hard and plays even harder.
Branded as "challenging and fun" the latter might be a bit of a stretch. Unless being incredibly challenged and frustrated by your own incompetence falls under your definition of "fun", of course.
6. The Irregular Rubik's Cube Will Drive You Crazy
The Irregular IQ Rubik's Cube is billed as a groundbreaking change to the classic game. If you struggle with the original it's probably best to give this one a wide berth.
If you fancy trying your hand at this one you are a brave Rubik's Cuber indeed.
7. The Idiot's Rubik's Cube Is Tantamount to Sacrilege
For Erno Rubik, the Idiot's Cube is possibly the very antithesis of his vision for the world-renowned toy. Lacking any colored stickers, it is literally impossible not to solve.
An ideal gift for anyone who struggles with the Erno's original brain-game, this cube is the perfect 'ironic' gift. Never again will the owner never be able to solve a Rubik's Cube - sort of.
8. The CuberSpeed Moyu 13 by 13 Magic Cube is a Sight to Behold
The Cuberspeed Magic Cube certainly takes Erno Rubik's concept to new heights. It's certainly imposing to look at and even more intimating to try to solve.
Judging by its size this will certainly keep the most dedicated Rubik's cube enthusiast's hands busy for many hours, if not years. You could just use it as an overpriced paperweight at the end of the day.
9. The Braille Rubik's Cube Expands its Frustration to the Visually Impaired
Specifically designed for the blind this cube is a true 'leveler' of a puzzle. Now not being able to see is no excuse for trying your hand at this classic puzzle.
10. This Mega Sudoku-Rubik's Cube Hybrid is a Challenge on Many Levels
The obvious upgrade to Erno Rubik's classic is to mix it with another challenging puzzle - Sudoku. This is where this ingenious amalgamation of Sudoku and the Rubik's Cube comes in.
The V-Cube Sudoku themed 3 by 3 by 3 Rotational Speed Cube is the perfect blend of these two loved puzzles. It will test you on many levels and is certain to be a worthy challenge for any Sudoku and Rubik's cube enthusiast.
11. The V-Cube Maze Puzzle Rubik's Cube Should Be a Worthy Challenge
The V-Cube 3-Maze Cube is probably one of the most interesting takes on Erno's original. It comes in 75 different designs and should certainly be a great challenge for any Rubik's Cube veteran.
It looks great and would be a great addition to any Rubik's Cube variant collection. Its labyrinthine combination of a classic puzzle is certainly worth a crack - good luck.
