The Edge

In a deck of 52 cards each time 1 card is turned.
You must fill all places with the cards turned.
Kings, Queens and Jacks must be placed on the predestined places.
If you can't place one of these on a predestined place you loose
the game. After filling all places you can erase cards which make
the sum of 10. Examples are a 10 or a 9 and ace.

You may remove as much cards as possible or stop after erasing 
lesser cards. After this you must fill the places again.

You win the game if you have placed all kings, queens and jacks
on the edge.

Controls:
Q=up
A=down
O=left
P=right
Z=set card / select card
SPACE=end erasing
U=undo selected card(s) without ending erasing

You can also use the controls to go from begin to end 
in a row/column by going 'out of the field'.

Have fun,
Dr Beep.
