BRAINTEASERS
By G. Ludinski
IN part number five of our BRAINTEASERS serial, we present two tests of
memory not dissimilar to the popular newspaper Spot the Difference
activity. As always, brief instructions are given on screen before each
of the puzzles commences and technical information detailing how the
program actually works, plus suggested improvements, follow in this
text file. The full collection of BRAINTEASERS is also reviewed in the
Reviews section of this issue.
ODD ONE OUT
NINE patterns are displayed on the screen and you are given only a few
seconds to compare them and identify the odd one out.
A score sheet will be displayed, showing the number of puzzles com-
pleted, number correct and the time and average time taken.
How to play
EACH of the patterns on the screen will be identified by a number, and
you must key in the appropriate number as your guess.
If you get the answer wrong, you will be told the correct answer to
the accompaniment of a rather low pitched little tune. Get it right,
however, and you will hear a pleasant little tune.
After each attempt you will be asked if you wish more (Y for Yes) or
wish to stop (N for No).
Remember to press <RETURN>.
Programming hints
THE filled in triangles are drawn by MOVEing to one point, then MOVEing
to another point, then drawing a line to a third point using PLOT 85,
and this fills in the space between the first point and the line between
the second and third points. This is done in the procedure PROC_PATTERN.
The pattern is transferred across and down the screen by adding the
appropriate XD or YD ot both, depending on the position of the screen.
You could put some more triangles into each pattern by increasing the
maximum value of L in procedure PROC_PATTERN. You would also have to
reDIMension arrays X,Y and C in line 30. Also the maximum value of I
should be increased in line 230.
PATTERN PAIRS
IF you enjoyed ODD ONE OUT in this series, then you will find this
following puzzle just as interesting.
There are nine patterns displayed on the screen, in a range of
colours, and you have to nominate the pair you believe are a match.
How to play
IDENTIFY your pair, note the numbers alongside and key in your answer.
You don't have to key in your answer in strict chronological order; just
punch in your numbers and wait. Correct responses will be rewarded with
a pleasant little high pitched tune, but wrong answers will be faced
with a low pitched little durge.
To continue, type Y at the "More?" prompt. On pressing N, a score
sheet will be displayed showing your tries, results, time and average
time per problem.
Programming hints
EACH of the pattens is slightly different except for the matching pair.
This is done by adding a mixture of H1, H2 and H3 to the corners of the
triangles in procedure PROC_PATTERN and H1, H2 and H3 will be different
for each pattern except the two that are the same.
If you wish to increase the number of patterns which are the same,
then a W3 should be assigned. W3 should be a random number between 1 and
9 inclusive and you should check that it is not equal to W1 or W2. Then
change W$ and W1$ and assign four more values, say W2$, W3$, W4$ and W5$
with the string of W1, W2 and W3 arranged in all possible different
ways.
Then check for PT to be equal to W1, W2 or W3 in line 720 in
procedure PROC_PATTERN to see whether the pattern to be drawn is one of
the three identical ones.
Change the input lines 440 to 510 to allow a third number to be keyed
in and then check for the six possible values W$, W1$ to W5$.
