There are +two contestants in each episode that compete in three game types: letters +rounds, in which the contestants attempt to make the longest word possible from +nine randomly chosen letters; numbers rounds, in which the contestants must +use arithmetic to reach a random target number from six other numbers; and the +conundrum, a buzzer round in which the contestants compete to solve a +nine-letter anagram. + +### Letters Round +The contestant in control chooses between two stacks of letter tiles, one +containing vowels (A-E-I-O-U only) and the other consonants, and the assistant +reveals the top tile from that stack and places it on the board. This is done +nine times, and the final grouping must contain at least three vowels and four +consonants. The contestants then have 30 seconds to form the longest single +word they can, using the nine revealed letters; no letter may be used more often +than it appears in the selection. + +#### Example +Contestant One chooses five consonants, then three vowels, then another +consonant. + +Selection is: `G Y H D N O E U R` + +Contestant One declares 7, while Contestant Two declares 8. + +Contestant One reveals `younger`, but Contestant Two reveals `hydrogen` and +scores 8 points. Contestant One does not score. + +### Numbers Round +The contestant in control chooses six of 24 shuffled face-down number tiles, +arranged into two groups: 20 "small numbers" (two each of 1 to 10), and four +"large numbers" of 25, 50, 75, and 100. Some special episodes replace the large +numbers with 12, 37, 62, and 87. The contestant decides how many large numbers +are to be used, from none to all four, after which the six tiles are randomly +drawn and placed on the board. Then, a random three-digit target number is then +generated by an electronic machine. The contestants have 30 seconds to work out +a sequence of calculations with the numbers whose final result is as close to +the target number as possible. They may use only the four basic operations of +addition, subtraction, multiplication and division, and do not have to use all +six numbers. A number may not be used more times than it appears on the board. +Division can only be performed if the result has no remainder. Fractions are not +allowed, and only positive integers may be obtained as a result at any stage of +the calculation. + +#### Example +Contestant One requests two large numbers and four small numbers. + +Selection is: 75 50 2 3 8 7 + +Randomly generated target is: 812 + +Contestant One declares 813, while Contestant Two declares 815. + +Contestant One is closer and so reveals: 75 + 50 – 8 = 117, and 117 × 7 – (3 × +2) = 813, which scores 7 points for being 1 away. Contestant Two does not score. + +# Solvers +- `numbers-round.py` is a solver for the Numbers Round. diff --git a/Countdown/numbers-round.py b/Countdown/numbers-round.py new file mode 100644 index 0000000..3ea0fd1 --- /dev/null +++ b/Countdown/numbers-round.py @@ -0,0 +1,92 @@ +#!/usr/bin/python + +import sys +import copy +import argparse +import itertools + + +def parse_arguments(): + parser = argparse.ArgumentParser(description = 'Countdown - Numbers Game', + add_help = False) + + parser._optionals.title = 'Target and List Numbers' + + parser.add_argument('-h', '--help', action = 'help', + default = argparse.SUPPRESS, + help = 'Countdown Numbers Game.
