is a game of deduction to break a code. Don Greenwell, a Professor
of Mathematical Sciences and Foundation Professor at Eastern Kentucky
University and Alex Bogomolny who holds a Ph.D. in Applied Mathematics
from the Hebrew University of Jerusalem provide a detailed explanation
of the game at Cut
the Knot. Try your skill playing the computer.
The object of
this game is to guess the sequence of four colored pegs the computer
has selected at random from the circled colors in the right field.
You start filling
the holes at the bottom row with pegs, and each time you have completed
a guess (i.e. filled all four holes) the computer will respond
by giving you one peg for each correct color - black if your guess
was also in the right place, otherwise white. (But you will not
be informed about which colors were correct. That part
you will have to figure out for yourself.)
If you haven't
managed to guess the sequence by your 8th guess, the computer will
reveal it to you and the game ends.
First select which colors you want to play with. (The default set contains
blue, green, red and yellow. That's moderately difficult. For
obvious reasons you are not allowed to select fewer than two. :-)
Clicking on a color in the field on the right will toggle the circle around
it on/off, indicating whether it will be part of the set the computer draws
from. Then press 'Start' to begin.
In case you
wish to start over, just press 'End' to discontinue the game.
