Constellations of Ostrel

Join the stars into the shapes of old myths.

Constellations is a calm logic puzzle. Every star shows a number: how many lines it needs. Draw straight lines from star to star, never let two lines cross, and when every number is met a figure lights up in the night sky (a kite, a whale, an owl, a dragon) along with a short myth from Ostrel, a fishing town on a cold northern bay.

PURE LOGIC, NO GUESSING
• Every sky has exactly one answer, and you can always reason your way to it.
• Lines are straight, never cross and never pass through another star.
• The silhouettes at the top show the shapes you're looking for.

A NEW TWIST IN EVERY SKY
• 200 nights across 10 skies. Each sky of twenty nights adds one new idea: pairs of figures, dim decoy stars that block lines, faint stars that hide their numbers, turned and interlaced figures, deep skies to zoom into, and hidden silhouettes.
• The first nights teach every move, one at a time.

A STORY IN EVERY FIGURE
• Finish a sky and its figures shine.
• 100 figures, each with its own short myth.
• Your star atlas keeps every figure you find, grouped by sky.

STUCK? ASK THE STARS
• Hints are free and unlimited.
• A hint points out a line that doesn't belong, or draws the next correct line and explains why it has to be there.
• Undo, clear and tap-to-remove make it easy to experiment.

CALM BY DESIGN
• No ads, no timers to beat, no lives, no accounts.
• Plays offline. No data is collected.
• Made for phones and tablets: portrait on phones, any orientation on tablets, with pinch-to-zoom for the biggest skies.
• Gentle chimes and haptics, with a high-contrast line colour option.

New skies are on their way.
