by L Cunningham, Rainham, Essex
from Your Computer (March 1982), Pages 69-70

Based on a well-known television game in which contestants predict the
relative values of playing cards, this program will run on a ZX-81 with 16K
RAM.

The screen displays two rows of concealed playing cards. In turn each card
is revealed from left to right in response to the pressing of keys L 
lower  or H  higher. The first card in each row may be changed by
pressing key C  change.

Pressing key S  stick  will protect the cards already revealed and
transfer play to the opponent. An incorrect prediction will result in all
cards to the right of the stick marker being cancelled and play returning
to the opponent. The object of the game is to complete five rows of cards
before the opponent.
