(How to do solitaire)
When you put the all 4 kinds of cards
sequentially to "1"… "K" at the upper-left card place,
it is clear.
At first, let's look for the card of "1".
When there is no card which can move to the upper-left card place,
you should touch upper-right cards
or move cards from the certain row to other row.
When you touch upper-right cards,
3 movable cards appear.
When you move cards from the certain row to other row,
you have to arrange it for red black alternation
in the order that the number of the card has a big.
