Why play Decade?
Decade is a quick calculation solitaire game where the puzzle comes from spotting efficient number runs before the line becomes crowded.
New variant
Decade Solitaire
Cards are laid out in a single growing line. Remove any run of consecutive cards whose values sum to exactly 10, 20, or 30 — face cards (J, Q, K) each count as 10. After every removal, deal one more card from the stock onto the right end of the line. Clear all 52 cards to win.
Click a card to start selecting a run. Cards in a consecutive run summing to 10, 20, or 30 are removed.
Rules overview
Remove consecutive card runs that total 10, 20, or 30, then deal a new card to the line until the entire deck has been cleared.
Strategy tips
- Look for removals that expose multiple future totals, not just the first valid one.
- Face cards all count as 10, so they can anchor many short runs.
- Avoid overfilling the line when a strong removal is already available.
