Each sky holds 16 stars, each labelled with a word. They secretly form four constellations of four: things like Birds of prey, ___ fish or Hides an animal.
Tap four stars you think belong together, then Link. If you're right, light threads snap between them and the constellation rises into the dome with its name. If you're wrong, you lose a comet. If three of your four were right, the dome whispers "One star astray…". Linking the same wrong four twice is blocked at no cost. Shuffle rearranges the stars.
Watch out for decoys: words that seem to fit two groups. The last group in a sky is always free.
The gold constellation. Every sky has one gold group, the trickiest, often wordplay. You don't know which it is until you find it. Find it first for ×4 points, second ×2.5, third ×1.5, last ×1.
The clock runs across the whole run, starting at 100 seconds. Every constellation adds 12 seconds and every cleared sky adds 15. If it runs out, the rest of the sky is shown, you lose a comet, and the clock resets to 60 seconds for the next sky.
Comets: you have 5 for the whole run. A sky cleared with no mistakes gives one back (up to 5). Lose them all and the run ends.
Hints: 3 per game, −250 points each. A hint names one hidden constellation (never the gold one) and marks one of its stars.
A run is 5 skies. They get harder: more decoys, then wordplay, and sky 5 has 20 stars in 5 groups.
Scoring: each constellation is worth 400 in sky 1, rising to 800 in sky 5, times its gold multiplier. Each sky cleared adds +1,000. At the end, every comet left is worth +500, and if you clear all 5 skies, every second left on the clock adds +5.
