How many combinations does the Rubik’s cube have? It’s easy to find out how many the 3x3x3 has, but when I looked, there were precious few pages that showed the number of combinations for all the sizes from 2x2x2 to 7x7x7. So, I made this page, listing the numbers of combinations for various sized cubes. There’s also a javascript calculator in case you want to figure it out for larger sizes.

The 2x2x2 Rubik’s cube (called the Pocket Cube) has 3674160 combinations . This is a manageable number. If you fiddle with the 2x2x2 cube randomly, eight hours a day continuously, you’ll solve it by pure chance roughly two or three times per year. Assuming your cube – or your wrist – doesn’t break in the meantime. Mind you, four months to solve the 2×2 cube is somewhat slower than the world record.

The original 3x3x3 Rubik’s cube has 43 252 003 274 489 856 000 combinations , or 43 quintillion. Again, as pointed out on this website’s main page, this is a manageably imaginable number. It’s a little less than the square of the earth’s population, for example.

The 4x4x4 Rubik’s cube (called the Master Cube, or Rubik’s Revenge – not sure who he was avenging, I must say) has 7 401 196 841 564 901 869 874 093 974 498 574 336 000 000 000 combinations (that is, 7.4 quattuordecillion, if you really wanted to know). To understand how big this number is, imagine you had this many teaspoons of sugar (say you’re planning a really big tea party). The sugar would fill the solar system out to about 3.5 times the orbit of Pluto. It would also weigh about 70 times as much as our galaxy, and instantly collapse into a black hole with an explosion that would wipe out the Milky way, the Magellanic clouds, and probably wake up some sleepy Andromedans as well. Think about that next time you twist the 4×4.

As if that’s not enough, the 5x5x5 Rubik’s cube (called the Professor’s Cube) has 282 870 942 277 741 856 536 180 333 107 150 328 293 127 731 985 672 134 721 536 000 000 000 000 000 combinations (aka 283 trevigintillion). This is getting uncomfortably close to the number of atoms in the known universe.

Recently, a Greek engineer Panagiotis Verdes figured out how to make 6×6 and 7×7 cubes. The V-Cube 6 (a 6x6x6 Rubik’s cube) has 157 152 858 401 024 063 281 013 959 519 483 771 508 510 790 313 968 742 344 694 684 829 502 629 887 168 573 442 107 637 760 000 000 000 000 000 000 000 000 combinations .

This is a ridiculously humungous number, of course, but… The 7x7x7 Rubik’s cube (the V-Cube 7) has 19 500 551 183 731 307 835 329 126 754 019 748 794 904 992 692 043 434 567 152 132 912 323 232 706 135 469 180 065 278 712 755 853 360 682 328 551 719 137 311 299 993 600 000 000 000 000 000 000 000 000 000 000 000 combinations. As I point out in this movie, that’s more combinations than eight independent 3x3x3 cubes. And yet, some people can still solve the 7x7x7 in just a few minutes. Amazing!

Nobody’s built and marketed any larger cube than that, although Panagiotis Verdes promises that some larger ones are in the pipeline. In the meantime, there are software programs that will let you play with any sized cube. These larger sizes are no harder to solve than the 6×6 and 7×7, just more tedious.

An 8x8x8 cube would have 35 173 780 923 109 452 777 509 592 367 006 557 398 539 936 328 978 098 352 427 605 879 843 998 663 990 903 628 634 874 024 098 344 287 402 504 043 608 416 113 016 679 717 941 937 308 041 012 307 368 528 117 622 006 727 311 360 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 combinations.

Youch!

If you want to find the number of combinations for a larger-sized cube, you can do so using the form below. I should warn you that if you type in a ridiculous size for the cube (say more than about 30), it will bog down your computer, not mine.

Note – due to bugs in Internet Explorer, you may need to use Google Chrome or Mozilla Firefox to get this form to fix – until I can figure out a way to work around the bugs. Anyway, Chrome and Firefox are much better than IE, so it’d be a mistake for you not to get them.
