The cards are laid out in the form of a clock with twelve at the top, and six at the bottom. The "5 Minutes Past" cards go to the one o'clock position, the "10 Minutes Past" cards go to the 2 o'clock position, and so on.

The cards are dealt face down and randomly to the 13 places. You start by left-clicking on the card in the center to turn it over. Holding your left mouse button down, and with the pointer over this card, you drag the card to its correct pile in the clock face. You then left-click on the top card of the same pile, and drag it to the right pile.

The game is over when you have placed all the cards in the right place before finding all four clock centers or when all the centers have been revealed. Points are added when you drag the card to the correct place. The quicker you find the right place, the more points you can score, up to a maximum of 1000 for each card.
