times, earning 2 points for a win and 1 for a draw. Part way through the
season the table is such that, with letters consistently replacing digits and
different letters used for different digits, part of its reads as below.

Although Attack is ahead of Brave which is ahead of Calamity (if teams have
equal points then goal difference determines the order), Calamity has played
more games than Brave which has played more games than Attack.

What were the scores in the games between Attack and Brave?

A 拢10 book token will be awarded to the sender of the first correct

Answer to Enigma 860 Weight for it!

Q1: 1,2,4,5,16,32,64,128,256,512; Q2: NO; Q3: NO.

Corrections

WITH all the usual best attempts by authors, referees and editor to ensure
the weekly Enigma puzzles are watertight and have unique and definite
solutions, we seem to have hit a bad patch:

852 The answer given proved not to be the minimum total edge-length sought,
rather it should be 81 instead of 83 yards. Congratulations to the 22 entrants
with this answer. The Editor decided on a random draw of these entries and now
declares D. W. Porter of Norton, Cleveland, the true winner.

860 The first line of Q3 should read, 鈥淎s Q2 but now I can replace six
鈥︹. The winner has been selected only on Q1 and Q2.

863 The penultimate sentence was meant to imply that fewer than half the
balls were heavier than 25. Apologies to all puzzled puzzlers.
Ed.

Enigma: No 835 /article/1836221-enigma-no-835/?utm_campaign=RSS|NSNS&utm_content=currents&utm_medium=RSS&utm_source=NSNS Fri, 11 Aug 1995 23:00:00 +0000 http://mg14719906.200 Treble top

WHENEVER I play darts I keep track of my score by writing down how many points I scored for each go (consisting of three darts) followed by the number of that go. For example, if I scored 27, 154 and 84 on my first three visits I would have written 2711542843.

After a recent game I noticed that if the digits were consistently replaced by letters, with different letters for different digits, then it read:

TREBLETOPSATDARTS

My total score was a prime number. Please send in PLEASE.

Enigma: Arrow route /article/1834471-enigma-arrow-route/?utm_campaign=RSS|NSNS&utm_content=currents&utm_medium=RSS&utm_source=NSNS Sat, 21 Jan 1995 00:00:00 +0000 http://mg14519615.400 I RECENTLY entered a local darts tournament where, to make things more difficult, most of the standard board had been covered up, leaving only six of the segments and the outer bull on which to score. No two adjacent segments were uncovered. In my seven visits to the board each of my darts scored (with three darts for each of the first six visits, but I did not need all three on my last visit). I kept a note of the remaining total required after each dart (starting at 301 and ending at 0, not necessarily finishing with a double).

In this list of decreasing numbers I noticed that after each visit to the board the remaining total required was a perfect cube. I also noticed that all the other remaining totals required were 鈥渢riangular numbers鈥 (that is, the sum of some consecutive integers from 1 upwards). The sum of the numbers on the six uncovered segments was also a triangular number.

Which segments were uncovered?

(A standard dartboard has twenty segments which are, in clockwise order from the top, 20, 1, 18, 4, 13, 6, 10, 15, 2, 17, 3, 19, 7, 16, 8, 11, 14, 9, 12, 5. Each segment has a single section, a double section and a treble section. The outer bull scores 25).
