Circa 1981: I was at a K-mart waiting in line to buy a handful of commodities, and there they were... an entire shelf of Rubik's Dominoes. There were about 100 of them on sale at the reasonable price of $2 each. I thought, "Nyet! $2 is still way too much for this puzzle." Famous last words; nowadays a Rubik's Domino will easily fetch at least $100 on e-bay.

A Rubik's Domino is basically a Rubik's Cube minus the "equator". Here are the laws of the Domino:
Solve the white pips (with the dark background) counting from left-to-right; in other words 1-2-3 for the top row, 4-5-6 for the middle row and 7-8-9 for the bottom row.
Hold the puzzle so that you are looking at the face with 5 white pips at the center. This side will be the front face for awhile.
If the #2 tile is already on the front face, then merely rotate the front face until the #2 tile is at the top row. | However, if the #2 tile is on the bottom face... | ||
...then flip whatever row or column that tile happens to be on. | Once the #2 tile is on the front, rotate the front face so that the #2 tile is at the top row. |
Knock Down: |
Move Up: | ||
If an edge tile is already on the front face, but at the wrong spot... | ...then knock it down, by flipping over whatever row or column it happens to be on. Afterwards, move it up to its correct spot during the next step. | If (or once) an edge tile is on the back, then rotate the back face until the edge tile is directly below its destination... | ...and then flip the row or column of that tile to move it up to its correct location. |
Now it's time to introduce yourself to the very first move you have to memorize:
R F+ B F- R |
What the move does: |
It swaps the lower-right corners from front to back and visa-versa. It also wreaks havok on other tiles on the back-side, but we do not care about their particular fate for now (as long the other front-side corners remain intact). |
Knock Down: | |||
Do the move: |
|||
A corner tile is already on the front side, but at the wrong spot. | Rotate the front face until that tile is at the lower-right. | R F+ B F- R |
Now the corner tile is knocked down to the back face. Follow the next step to move it up. |
Move Up: | |||
Do the move: |
|||
A corner tile is on the back face. SET UP: Rotate the back face so that the tile to-go is at the lower-right. Rotate the front face so that the vacant tile is also at the lower-right. |
R F+ B F- R |
Now that the tile is moved up to its proper location... | ...rotate the front face until all solved tiles are where they're suppose to be, just to get your bearings straight. |
