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. - A
**9x9x9**cube would have**14 170 392 390 542 612 915 246 393 916 889 970 752 732 946 384 514 830 589 276 833 655 387 444 667 609 821 068 034 079 045 039 617 216 635 075 219 765 012 566 330 942 990 302 517 903 971 787 699 783 519 265 329 288 048 603 083 134 861 573 075 573 092 224 082 416 866 010 882 486 829 056 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000**combinations. - A
**10x10x10**cube would have**82 983 598 512 782 362 708 769 381 780 036 344 745 129 162 094 677 382 883 567 691 311 764 021 348 095 163 778 336 143 207 042 993 152 056 079 271 030 423 741 110 902 768 732 457 008 486 832 096 777 758 106 509 177 169 197 894 747 758 859 723 340 177 608 764 906 985 646 389 382 047 319 811 227 549 112 086 753 524 742 719 830 990 076 805 422 479 380 054 016 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000**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.

I think the math is off on this. The puzzle is not a 3x3x3 puzzle. It’s 8 corner pieces that can change positions and be oriented 3 ways combined with an independent 10 side piece puzzle that can be oriented in 2 ways. I don’t understand why, but part of the geometry of the puzzle dictates that no piece can rotate independently – any piece that does must rotate another piece. I think this effectively cuts the number of possibilities in half.

To simplify this down to the 2×2 puzzle, you have 8 pieces to make up the puzzle. Each puzzle piece can have 3 orientations. So the answer is the number of different places to put the puzzle pieces times the number of different combinations of orientations that the pieces can have (divided by 2 because of the rotation dependency).

I’m still struggling with the right math, but I think this it. There are 8! different ways to arrange the 8 corner pieces. Each piece can have 3 orientations, which is 3^8 different ways to combine them. So, I get a much larger number at 40320 * 6561 / 2 = 132,269,760 different positions that the 2×2 puzzle can have.

Expanding this to the 3×3 is actually the 2×2 puzzle times a 10 side piece / 2 orientation puzzle calculated the same and still with the same rotation dependency. So that is the 2×2 answer * (3,628,800 * 1024 / 2) which is 245,750,018,605,056,000 (245.75 quadrillion), significantly less than a 3x3x3 grid answer. But still really big.

Not 100% sure on this, but my best guess – I know the 3x3x3 is out because that isn’t how the cube is made up.

Well, for the 2x2x2, the eight corner pieces can’t be all independently rotated – you can choose an arbitrary rotation for seven of them, and then the 8th is determined. So that’s 8! x 3^7.

And for the 3x3x3, why do you say there are ten edge pieces? Surely you mean twelve?

How about Apple Safari! Ask me and I’ll tell you it takes not even a full-second when entering 100!

Brian Flynn’s math is way off.

A commonly asked question is “How many ways can a 3 x 3 x 3 Rubik’s Cube be arranged” and the answer is usually given as 43,252,003,274,489,856,000. I should like to put the question in a different way, “Given a Rubik’s cube in its solved position, in how many ways can you scramble it?”

The cube has six faces and so there are 6! ways of choosing the order in which to twist the faces. Each face has four positions, so I get 6! x 4^6 = 2,949,120 ways of scrambling the cube. I feel that this should be an upper limit to the number of legal combinations of the squares, since the only way to get a legal combination is by twisting the faces.

You’ve assumed you can only twist each face once – but that’s not the case. After you do your first twists, you can do more on faces already twisted to access even more combinations.
