Cycle the stock as many times as you like in this loosened-up Big Harp, until the tableau opens up for one of the site's friendlier 80% win rates.

Endless Harp Solitaire takes Big Harp Solitaire and drops its stock limit: here you can run through it as many times as you need, dealing three cards at a time until the tableau finally opens up. That one change turns a tough two-deck Klondike into a fairly friendly one, with an 80% chance of winning. It's played with two decks, and your odds come down mostly to skill.
It shares its ten-pile layout with Big Harp, and plays a lot like Eternal Triangle Solitaire, another two-deck sibling with the same pile spread. The family takes its name from Harp Solitaire, a two-deck, nine-pile relative with a smaller tableau.
If you run into anything odd or have an idea that would make the game better, please contact me.

8 foundation piles: Build up from Ace to King in the same suit.
10 tableau piles: Build down in alternating colors. Sequenced cards move together by alternating color. Only a king, or a sequence led by a king, can fill an empty pile. At the start of the game the piles are dealt one card, two, three, and so on up to ten; only the top card of each pile is face-up, and the rest are face-down.
Stock: Click to flip three cards to the waste. Redeals are unlimited.
Waste: Top card available for play on the foundations or tableau.
There are eight foundation piles.
Any ace can be placed on an empty foundation pile.
A card can go on a foundation pile if it's one rank higher than the pile's top card and the same suit. So the only card that fits on a 4 of clubs is a 5 of clubs. No pile can hold more than 13 cards.
The top card of a foundation can move back into play if another pile will take it.
Ten tableau piles, dealt one card in the first, two in the second, three in the third, and so on up to ten in the tenth. Only the top card of each pile is dealt face-up; the rest are face-down.
A card can go on a tableau pile if it's one rank lower than the pile's top card and the opposite color. So a jack of spades or clubs can be played on a queen of diamonds or hearts.
Any card not covered by another is free to move to the foundation or another tableau pile.
Only a king can fill an empty tableau spot.
Sequenced cards, alternating red and black, can be moved from one tableau pile to another as a group.
There's one waste pile; the rest of the cards make up the stock.
Click the stock to deal three cards to the waste. You can go through the stock as many times as you like. If the stock runs short near the end of a pass, whatever cards are left get dealt. Once a pass ends, the waste pile turns back into the stock for the next one.
The top card of the waste can be played to the tableau or foundation.
