You
can also play Dice Soccer without a computer.
Use
just a dice, two chess-boards, a coin (the ball) and the
chess-pieces as players.
Roll the dice, then pass the ball into a square or to a
player by the number on the dice.
The nearest player then moves onto that square and takes
the ball.
If two players from opposite sides are equal squares away
from the ball, then contest the ball with another dice roll
for each side, so that the highest roll takes the ball and
that square.
Suggestions for setting up the pieces: Place 8 pieces from
each side on the 2nd square from the goal. Then roll a dice
for each and advance that piece by that number. The last
two pieces are placed in turn by each side, but may not
be more than 2 squares into the opponents half. Roll to
see who chooses to place their forwards first, the other
side gets to start the game with a forward near the center
spot.
Innovate the rules to suit your needs, but because its awkward
to keep time without the computer to count moves, play to
(perhaps) the first to score 2 goals.
Practise against the computer for a bit, and then challenge
your grandpa to the chessboard variety if he does not quite
get these fandangly computer thingys.
Play
Fair.
