Kilominx Solver

Get a full solution for any scrambled Kilominx. It takes the same road as the tutorial: the white layer, the two middle rings, then the gray top.

Paint the colors of your puzzle onto the net, press Solve and follow the moves. You can use the palette, the turn buttons or a typed algorithm.

If a painted position is impossible, the solver names what looks wrong. It may be a twisted corner, swapped corners, or a miscounted color.

How to Solve the Kilominx?

The beginner's method in five steps: build a white layer, fill the two middle rings corner by corner, then place and turn the gray top. Every piece is a corner. If you can solve a 3x3 or our Megaminx, this is the friendly one.

A black Kilominx, the corners-only dodecahedron, with yellow, purple and white faces showing

The Kilominx is the corners-only little brother of the Megaminx, and Meffert's sells it as the Flowerminx. It has the same twelve-sided shape, but each face is just five corner stickers meeting at a point. Twenty corners, and nothing else. It still hides 2.36×1025 positions, yet the solve is far shorter than the Megaminx's.

The method below follows the same road as the Ruwix Kilominx guide, adapted to this page's face names. Every sequence has been machine-checked against the simulator, and the diagrams come from the same engine that turns the puzzle.

If you have solved our Megaminx, you already know every trick on this page. There are no edges to worry about here.

How to Read the Moves

A dodecahedron has twelve faces, so the moves need twelve letters. Six of them point your way: U up, F front, R right, L left, BR and BL curving around the back. The other six live on the far side of the puzzle: D down, B back, DR and DL below the front, DBR and DBL below the back.

UFRLDRDL

from the front

ULBLBRDBL

from behind

DBDRDBR

from below

A bare letter spins that face one fifth of a turn clockwise (72°). Add an apostrophe (') and it goes the other way; add a 2 and it goes twice as far. Careful: a face has five stops, so U2 and U2' are different moves. Two steps one way is not the same as two steps the other.

The timer's scrambles use the Megaminx competition notation: R++ and D++ take hold of everything except one far layer and move it two steps. A -- sends it back again, and a plain U closes off each line. The simulator speaks the same notation.

💡

There Are No Centers at All

On the Megaminx the twelve fixed centers tell you where every color lives. The Kilominx has no centers and no edges, so nothing is anchored anywhere. That sounds harder, but it works in your favor. Nothing can be "in the wrong spot relative to the centers", because there are no centers to disagree with.

Your reference is the corners you have already placed. Two neighboring corners meeting on a face must show the same color on that face. That one rule replaces the centers everywhere below.

A kilominx has exactly 20 corners with three stickers each. They sit in three rings of five between the white bottom and the gray top, and this page's five steps take them in that order.

1

The White Layer

Pick white. Solve the first white corner anywhere, then build the other four around it, one by one. Each new corner's side colors must match the corners already placed where they meet on a face.

To insert a corner, turn it directly under the empty slot, one layer down. Then repeat these four moves until it clicks in place with white on top:

R' DR' R DR

One, three or five rounds seats it, whichever way the corner is facing, and the corners already placed come back untouched every time. On a 3x3 this trick is called R' D' R D; here the "down" face by the corner is named DR.

the corner waits under its slot...

➤

...and clicks in after 1, 3 or 5 rounds

2

The Lower Middle Corners

Turn the puzzle over: white face down, gray on top. Five corners form a ring just above the white layer. Each one is the bottom corner of one face. Its home is the notch between two solved white corners, so its two lower colors are decided by them.

Every corner you need is waiting in the gray top layer. Face the slot you want to fill and look at which of the corner's colors points straight up. Park the corner with a turn of the top, then drop it in:

parked at the top right of the front face...

➤

...one double turn drops it home

Park it at the front face's top right with the lower-right color pointing up, and run:

F2

Park it at the top left with the lower-left color pointing up:

F2'

And if the front color points up, park it at the top left and run:

F U F2'

If the corner you need is jammed in a slot the wrong way round, run that slot's own turn once with anything on top. It pops back into the gray layer, and then you can place it properly.

3

The Upper Middle Corners

The last ring before the top: five corners sitting directly under the gray layer's gaps. Same story as step 1, in the new grip. Park the waiting corner in the gray layer directly above its slot and repeat four moves until it clicks:

the corner waits right above its slot...

➤

...and settles in after 1, 3 or 5 rounds

R U R' U'

That is for a slot on the right side of the face you're looking at. For a slot on the left side, use the mirror:

L' U' L U

One, three or five rounds, depending which way the corner faces. Everything below survives, and we checked that by machine.

Same rescue as in step 2. If the corner you need is already jammed in one of these slots the wrong way round, run that slot's four moves once with anything waiting above. The stuck corner pops back into the gray layer, ready to be placed properly.

4

Place the Top Corners

Only the five gray corners are left. First send each one home, to the spot whose three side colors match its stickers, twisted or not. This pair of sequences cycles three corners and moves nothing else at all. On the left side of the top, clockwise:

L' U2 R U2' L U2 R' U2'

And on the right side, counterclockwise:

R U2' L' U2 R' U2' L U2

Turn the gray face to line the trio up with the picture, run, turn the top back, and check again. Two or three visits are always enough.

5

Turn the Corners Upright

Every piece is home; some corners just face the wrong way. Hold a twisted corner at the top front right and run the four moves from step 1, twice per third of a turn:

R' DR' R DR

Two rounds turn the corner one third of the way; run two more if it needs the other third. Then turn only the gray face to bring the next twisted corner to the front right and repeat. The layers below get scratched up while you work, but keep going. The scratch repairs itself by the time the last corner turns upright, every single time.

Turn the gray face into line, and the Kilominx is done.

What Next?

Congratulations. You just solved a puzzle with 23,563,902,142,421,896,679,424,000 positions using four short sequences.

Now make it fast against our timer. The Kilominx is not an official WCA event yet, so your living-room record is as good as anyone's. And when the corners feel easy, the Megaminx adds the edges back.

Online Kilominx Puzzle Simulator, Solver, Timer and Tutorial

Free online 3D Kilominx simulator, a complete solver, speedcube timer with official-style scrambles, and a five-step tutorial for beginners.
The Kilominx is the corners-only cousin of the Megaminx. It keeps the same twelve-sided shape, but only the twenty corners, the way the 2x2 strips down the 3x3.

It is also sold as the Flowerminx. The idea goes back to the early 1980s, but the modern speedcube version arrived in 2016, when ShengShou put it into mass production. 🎲 Take a Megaminx and pull off the centers and the edges. What is left are 20 corner pieces, five on every face, and 60 stickers in all. It has exactly 23,563,902,142,421,896,679,424,000 positions. That is about 2.36×1025, a 26-digit number, and the full Megaminx has roughly 1043 times more.

One thing makes it feel very different from its big brother. There are no fixed centers. Nothing anchors any color anywhere, so the whole color scheme travels with the corners. The puzzle itself decides where white ends up. Every piece is the same kind, and every face turns in five stops of 72 degrees.

Spin the dodecahedron in the simulator

The Kilominx at the top of the page is a real 3D puzzle. Push a sticker and the whole face comes with it, stopping every 72 degrees. Drag beside the puzzle instead and the model spins, so you can check the back. Scramble mixes the twelve faces, and Full fills the screen. Nothing here can break, so go ahead and fiddle.

Stuck? The solver walks you home

Hold your mixed-up Kilominx next to the flat net in the solver and copy it across. Pick a color from the palette and click the stickers. You can also turn the faces with the buttons, or type an algorithm in. Then press Solve. It takes the same road the tutorial below does: white layer, the two middle rings, gray top. No answer reaches the screen until the program has checked it against the puzzle itself. Expect 75 to 120 moves. Step through them one at a time, or slow the playback down until you can keep up. Paint something a real Kilominx could never do, and it tells you which piece is wrong. It may be a corner twisted in place, two corners swapped, or a color used the wrong number of times.

Race the clock

⏱️ Hold the space bar until the clock goes green, then let go and it starts. Press again to stop. On a phone, hold the clock face instead. Each attempt brings a new scramble written the Megaminx way. Seven lines of R++, R--, D++ and D-- swing most of the puzzle at once, and every line ends with a U or U'. Nobody holds a Kilominx world record, because it is not a WCA event. The only time worth beating is the one you set last week.

Learn the whole solution in five steps

🎓 Underneath the clock, the panel keeps your best single, your session average and the rolling averages of 5 and 12. The tutorial below teaches the beginner method in five steps. You build the white layer, then the five lower middle corners, then the five upper middle ones. After that you place the last-layer corners with two cycle sequences and turn them upright with a short four-move trick. Every algorithm on the page is machine-checked against this page's own simulator. With no edges to pair and no centers to match, it is the friendliest dodecahedron in the family.

Why is the Kilominx friendlier than it looks?

The Kilominx is not a WCA event, so it has no official world records. The Megaminx record comes from the WCA and was checked in August 2026. The live list is at worldcubeassociation.org.

OnlineCube.com also has the classic 3x3 cube, the pocket 2x2, the big 4x4 and 5x5. There is the Pyraminx, the Skewb, the shape-shifting Square-1 and the full twelve-sided Megaminx too. Each one has its own simulator, timer and tutorial. If the Kilominx clicked for you, its big brother is the natural next step.
