Mahjong Dimensions: 470 seconds
Mahjong Dimensions: 470 seconds
This is mahjong solitaire on a rotating cube, and it is the fast one.
Four hundred and seventy seconds is just under eight minutes. The same cube with fifteen minutes on it is a puzzle you can think your way through. With eight, thinking is the thing you cannot afford, and the game becomes about recognition speed instead.
That changes what good play looks like. In the longer versions you study the board and plan an order. Here you take the match you can see, immediately, and trust that the board will keep offering them.
How to play
- Tiles are stacked into a three dimensional block you can rotate.
- Match two tiles showing the same face to remove them.
- A tile is only selectable when nothing sits on top of it and one side is open.
- Drag to rotate and reach the faces you cannot see.
- Clear the cube before 470 seconds run out.
How to play Mahjong Dimensions: 470 seconds
Why the clock changes the game
Every rotation costs time you are not spending on matching. In the fifteen minute version you can afford to turn the cube looking for the efficient move. In eight minutes you cannot.
The practical consequence is that you should clear everything visible on the face in front of you before turning at all, even when a better match is one rotation away. Two mediocre matches taken now beat one good match found in six seconds.
Chains
Matches made quickly one after another score more than the same matches made slowly. On a tight clock that bonus is not a nicety, it is most of the difference between finishing and not.
When you spot three or four obvious pairs on one face, take them in a run rather than pausing to plan between them.
Tips and strategy
Speed play
- One orienting rotation at the start, then stop turning to browse. After that, only turn when the visible face is exhausted.
- Take from the top down. A tile lifted from the upper layer frees several beneath it, a tile taken from an edge frees almost nothing.
- Do not hunt for the perfect pair. On this clock the correct move is almost always the first legal one you see.
- When three identical tiles are showing, take the pair that opens the most rather than the pair that is easiest to click.
Clock checkpoints
- At the halfway mark, roughly 235 seconds, more than half the cube should be gone. If it is not, stop looking for efficiency entirely and clear anything legal.
- In the last minute, ignore the stack entirely and take whatever matches. A partially cleared board scores more than a carefully planned one you did not finish.
Traps
- Rotating between every match. It is the single largest source of lost time in the series.
- Treating this like the 900 second version. The same board with half the clock is a different game and it rewards different habits.
For the same cube with more time to think, try Mahjong Dimensions: 640 seconds or Mahjong Dimensions: 900 seconds.

Frequently asked questions
How long is 470 seconds?
Just under eight minutes. It is the tightest clock in the Dimensions series.
How is this different from the 640 and 900 second versions?
The board and the rules are the same. Only the time limit changes, and that changes how you should play: the shorter the clock, the less you can afford to rotate the cube looking for the efficient match.
When can a tile be taken?
When nothing is stacked on top of it and at least one of its sides is open. A tile boxed in on both sides cannot be matched even if you can see its face.
Do fast matches score more?
Yes. Matches made in quick succession are worth more than the same matches made slowly, which matters more here than in the longer versions.
Is it free to play?
Yes. Nothing to install, no account and no payment.
