Today's Navigator Rankings

What is Stellar Align?

Stellar Align is a daily web puzzle game by pi-dimension. As a cosmic navigator, you look at warped constellations through a special telescope — the celestial lens — and combine geometric coordinate transformations such as horizontal and vertical shifts, 45-degree rotation, 2x magnification, 0.5x shrink, reflection and skew, in as few moves as possible, until the stars line up exactly with their target shape. A new constellation is released every day at midnight (KST) across three difficulties, and daily and all-time rankings let you compete with navigators around the world. It is a free geometry puzzle that runs in your browser with no installation.

How to play

Choose a difficulty. Pick Easy, Medium or Hard and today’s constellation appears on the instrument panel.

Study the target. You need to place every star exactly on its target coordinate.

Combine transformations. Apply the eight operations below in sequence to move, turn and stretch the constellation.

Aim for the shortest path. The minimum number of moves needed is shown; fewer moves means a higher rank.

Submit your record. Once every star is aligned, leave a navigator name to enter today’s ranking.

The eight coordinate transformations

Shift X — Translates the whole constellation one step along the x-axis.

Shift Y — Translates the whole constellation one step along the y-axis.

Rotate 45° — Rotates the constellation 45 degrees counter-clockwise about the origin.

Flip horizontally — Reflects the constellation across the horizontal axis.

Magnify 2x — Scales the constellation up by a factor of two about the origin.

Shrink 0.5x — Scales the constellation down by half about the origin.

Skew left — Applies a shear transformation to the left along the x-axis.

Skew right — Applies a shear transformation to the right along the x-axis.

How do the difficulties differ?

Easy uses fewer stars and is designed to be solved in two or three transformations. Medium mixes rotation with reflection, so a wrong order forces you to backtrack. Hard adds scaling and skew together, and you have to understand that these transformations do not commute in order to find the shortest path. All three are refreshed once a day.

Frequently asked questions

What kind of game is Stellar Align?

It is a geometry puzzle in which you play a cosmic navigator realigning warped constellations through a celestial lens. You combine transformations such as shift, rotate, magnify, shrink and reflect in the fewest moves to match the target shape.

Do I need to install anything? Is it free?

No installation is required. Play instantly at stellar.pi-dimension.com in any web browser, free of charge. Add it to your home screen to launch it like an app.

Can I play on mobile?

Yes. Phones, tablets and desktop browsers are all supported, and the instrument panel layout adapts to the screen size.

Which languages are supported?

Korean, English, Japanese, Chinese, German and French. You can switch at any time from the settings menu.

Can I play puzzles from previous days?

Yes. Pick a past date in the puzzle calendar to load that day’s constellation and try it again.

Is there a new puzzle every day?

Yes. A new constellation is published every day at midnight (KST) for each of the three difficulties.

How is the ranking calculated?

Fewer moves means a higher rank. Today’s ranking counts only today’s records, while the cumulative ranking sums records across all time.

Who made it?

It was built by pi-dimension, a studio that starts from mathematical axioms to make games and apps. Other daily puzzles such as RuneGrid, MindPlayer and Pi Day are available at pi-dimension.com.
