Make combinations of 3 cards in the three columns, either consecutive (ascending or descending order) or identical cards (e.g. 3-4-5 or Q-Q-Q). Park cards you can't directly use in the three spots below. Shuffle your cards around until none are left, within the time given...
When the game is not cleared and you have no more cards left, you will be asked if you wish to add 6 more cards to try and clear the game. These 6 cards are random so this could prolong finishing the game or a possibility to clear it.
