he game of a million hastily concealed PC windows. Its popularity is perhaps due to its strangely hypnotic nature, even though it takes real persistence to win.
The game is played using a seven columns. Running from left to right, the first column contains one card, the second contains two, the third three, etc. In each column, the top card should be face up and the rest face down. Deal by placing one card, face up, on the table in front of you then, to this card's right, six more face down. Repeat this row by row, dealing one less card each time.
you'll work with every third card in the remaining pack, one at a time. Move through the pack by taking three cards from the top and turning them over, creating a new face-up pile. When you've passed through the deck, turn it over and start again.
