Answer all the questions.
1 Eve enjoys playing board games. Her favourite board game is called “Pot Luck”. This has a
numbered grid of 10 squares by 10 squares. Each square has a number between 1 and 100.
Players place their game counters on square 1. A 30-minute timer is set which counts
downwards. Each player rolls two 6-sided dice and then moves their game counter that number
of squares. Some squares tell the player to pick up a card. These have instructions on, such as
‘Move forward 10 spaces’. If the player lands on one of these squares they move according to
the instruction on the card. The first player to land on square 100, is announced as the winner. If
no winner is announced before the timer runs out, then it is a draw.
(a) Eve would like to create a computerised version of this game.
(i) She has been told that she should make use of abstraction when creating the game.
Describe what is meant by the term ‘abstraction’.
