A new card game for two players.
Follow-up to the February Game Rules of FEMTO.
This is a collection of games of skill for two players, both
players have exactly the same information, chance plays no part,
and each game must terminate. There is always a 'winning strategy'
and all the moves can be analysed mathematically. The only
advantage that either player can possibly have is to start or to
play second. To work out how to win you need to start by analysing
the 'end game', and the losing position to be avoided, and then
work back to earlier moves. Can you find the winning
The rules are simple. Start with any number of counters in any
number of piles. Two players take turns to remove any number of
counters from a single pile. The loser is the player who takes the
The rules are the same as for Common Nim but, in this game, the
winner is the player who takes the last counter.
This game always starts with an odd number of counters and they
can be arranged in any number of piles. The players in turn take
any number of counters from a single pile. The winner is the player
who ends up with an odd number of counters. First try the game
starting with three rows with 1, 3 and 5 counters and the rule
that, when it is your turn, you can only take one, two or three
counters from one of the rows. What if you change the game so it
starts with more rows? What if you change the restrictions on the
number of counters you are allowed to move? What if you have no
restrictions except that in any one turn you can only take counters
from one of the rows?
This is a simple version of Oddly. The game starts with an odd
number of counters in a single line. Play this game with the rule
that players take one, two or three counters at a time and the
winner is again the player who ends up with an odd number of
In this game the players may take a single counter or two
adjacent counters and the winner is the player who ends up with an
odd number of counters.
This game is played with a line of squares and a set of counters
or coins. Only one coin has any value. The game starts with some
empty squares and single coins in the other squares. Each player in
turn may either move any one coin any number of empty spaces to the
left, or take the coin on the extreme left. You cannot put two
coins on one square or jump coins past each other. The winner is
the player who takes the gold coin. You can play this game on a
line of squares with any number of squares to the right but the
left hand end is a cul-de-sac. As the coins can only move to the
left sooner or later all the coins will be shifted to the left with
no remaining spaces between them and someone will be able to take
the gold coin and win the game.
