Modern Puzzles by Henry Ernest Dudeney: $178$

The Seven-Pointed Star
We have already dealt briefly with stars of five and six points.
The case of the seven-pointed star is particularly interesting.
All you have to do is place the numbers $1$, $2$, $3$, up to $14$ in the fourteen discs so that every line of four disks shall add up to $30$.

If you make a rough diagram and use numbered counters, you will find it difficult to break away from the fascination of the thing.
Possibly, however, not a single reader will hit upon a simple method of solution:
his answer, when found, will be obtained by mere patience and luck.
Yet, like those of the large majority of the puzzles given in these pages,
the solution is subject to law, if you can unravel it.
