If you have a red 6 on a black 7 on a red 8, but you can move the six to a black 7 which is on a red 8 which is on a red 9, make that move. The higher the tower, the better it is for you. The best place to move a card is to a column which has a king on the top. Always try to pile your cards on a column which the top card is a king. There will be plenty of opportunities to do this near the end of the game.
Next priority is to put cards on a column in perfectly ascending order.
For example, if a column has a red 10 at the top, and below it a black 9 and below it a red 8, that would be a good place to put a black 7. If given a choice between two otherwise equal places to put a card, always put the card on the column which has the largest sequence of ascending cards with alternating color. My experience has been that once you have 12 cards safely on the cells on the upper right hand side of the board, you always win, no matter how bad your position may otherwise be. However, it is not always easy to see the way to win. Sometimes I look 5 or ten minutes or even longer thinking that I am hopelessly stuck and there is no way out.
