Constellations

Differences · 30 levels

Number the stars so every line tells the truth.

How to play

1. Give every star a number from 1 to n, using each number once. Tap a star, then a number.
2. A line marked −3 joins two stars that are 3 apart, like 2 and 5.
3. Later skies add + lines (the two stars add up) and × lines (they multiply). Unlabelled lines can be anything.

Big gaps are the giveaway: in a sky of 6 stars, a −5 line must join 1 and 6.
