This puzzle should be compared with Sharp's Puzzle, referred to in my
solution to No. 341, "The Four Frogs." The condition "touch and jump
over two" is identical with "touch and move along a line."
227.--CENTRAL SOLITAIRE.
Here is a solution in nineteen moves; the moves enclosed in brackets
count as one move only: 19-17, 16-18, (29-17, 17-19), 30-18, 27-25,
(22-24, 24-26), 31-23, (4-16, 16-28), 7-9, 10-8, 12-10, 3-11, 18-6,
(1-3, 3-11), (13-27, 27-25), (21-7, 7-9), (33-31, 31-23), (10-8, 8-22,
22-24, 24-26, 26-12, 12-10), 5-17. All the counters are now removed
except one, which is left in the central hole. The solution needs
judgment, as one is tempted to make several jumps in one move, where it
would be the reverse of good play. For example, after playing the first
3-11 above, one is inclined to increase the length of the move by
continuing with 11-25, 25-27, or with 11-9, 9-7.
I do not think the number of moves can be reduced.
228.--THE TEN APPLES.
Number the plates (1, 2, 3, 4), (5, 6, 7, 8), (9, 10, 11, 12), (13, 14,
15, 16) in successive rows from the top to the bottom. Then transfer the
apple from 8 to 10 and play as follows, always removing the apple jumped
over: 9-11, 1-9, 13-5, 16-8, 4-12, 12-10, 3-1, 1-9, 9-11.
229.--THE NINE ALMONDS.
This puzzle may be solved in as few as four moves, in the following
manner: Move 5 over 8, 9, 3, 1. Move 7 over 4. Move 6 over 2 and 7. Move
5 over 6, and all the counters are removed except 5, which is left in
the central square that it originally occupied.
230.--THE TWELVE PENNIES.
Here is one of several solutions. Move 12 to 3, 7 to 4, 10 to 6, 8 to 1,
9 to 5, 11 to 2.
231.--PLATES AND COINS.
Number the plates from 1 to 12 in the order that the boy is seen to be
going in the illustration. Starting from 1, proceed as follows, where "1
to 4" means that you take the coin from plate No. 1 and transfer it to
plate No. 4: 1 to 4, 5 to 8, 9 to 12, 3 to 6, 7 to 10, 11 to 2, and
complete the last revolution to 1, making three revolutions in all. Or
you can proceed this way: 4 to 7, 8 to 11, 12 to 3, 2 to 5, 6 to 9, 10
to 1. It is easy to solve in four revolutions, but the solutions in
three are more difficult to discover.
This is "The Riddle of the Fishpond" (No. 41, _Canterbury Puzzles_) in a
different dress.
232.--CATCHING THE MICE.
In order that the cat should eat every thirteenth mouse, and the white
mouse last of all, it is necessary that the count should begin at the
seventh mouse (calling the white one the first)--that is, at the one
nearest the tip of the cat's tail. In this case it is not at all
necessary to try starting at all the mice in turn until you come to the
right one, for you can just start anywhere and note how far distant the
last one eaten is from the starting point. You will find it to be the
eighth, and therefore must start at the eighth, counting backwards from
the white mouse. This is the one I have indicated.
