Decade is a solitaire game using one deck of playing cards.
The object is to discard all cards to the discard pile.
All 52 cards are placed face up.
If the total of at least two consecutive cards are equal to 10, 20, or 30, they are discarded.
Spot cards (ace, duece, etc.) have their face value while face cards (jack, queen, and king) are valued at 10.
Cards are selected by clicking it once. To unselect a card click it one more time.
Select cards in a sequence to make the sum of 10, 20 or 30.
Face cards can be discarded alone since they are valued at 10.
Once all cards are discarded, you win.
