Grey Olltwit's Clock Patience 2.2

Clock Face is a card game adapted to a program for helping to learn how to tell the time. To play the game you have to find all the cards for each position of the clock without turning over all four Clock Centres. The four clock centres are the cards with a blue dot in the middle. There are 52 cards as in a normal pack, 4 for each position e.g. 4 cards with 5 Minutes Past, 4 with 10 Minutes Past etc. Reveal all four Clock Centres before finding all the others and the game is over.
