A player can get a higher score by clearing long runs of cards. The color or suits make no difference.
Ace is considered to be 1 point away from both King and Two.
If no card can be played, a player can use the draw pile or a single wild card (Joker) that can be matched with any open card.
The game ends when (a) the time runs out or (b) if there are no more draw piles or (c) if there are no more moves.
Clearing a single card gives 10 points
Clearing two cards in a row gives 20 points, three - 30 points, etc.
Using the wild card or a card from the deck breaks the sequence, and the next card cleared would give 10 points
There is a time bonus in points for finishing the game earlier than the time limit
Try to use the wild card only when absolutely necessary
Given a choice, try to clear the cards in a way that would open up more possibilities for further clearing
Try to strike a balance between clearing card sequences and finalizing individual decks
If you remember the cards used, you'll be able to make a better choice: at times it may even be advantageous to sacrifice a wild
card in order to get a longer run or to finalize an intermediate deck
