- A New Leap-Frog Puzzle
- Make a rough board, as shown, and place seventeen counters on the squares indicated.
- The puzzle is to remove all but one by a series of leaping moves, as in draughts or solitaire.
- A counter can be made to leap over another to the next square beyond, if vacant, and you then remove the one jumped over.
- It will be seen that the first leap must be made by the central counter, No. $9$, and one has the choice of $8$ directions.
- A continuous series of leaps with the same counter will count as a single move.
- It is required to take off $26$ counters in $4$ moves, leaving the No. $9$ on its original centre square.
- Every play must be a leap.
