Eight piles arranged in a ring, and every card you place stays there for good. Circle Eight is a single-deck gauntlet with roughly a 10% win rate.

Circle Eight Solitaire belongs to the old family of one-way patiences in which every placement is final. Eight cards are laid out — traditionally arranged in a ring, which is how the game got its name — and the rest of the pack is turned up one card at a time. Each card you turn may be dropped onto any pile whose top card is one rank below it, regardless of suit, and the counting runs in a circle too: after a King comes an Ace, then a Two, and around again.
The sting is that a card, once placed, can never be moved again — there are no foundations to rescue it and no shuffling between piles. You get two trips through the stock, and you win by landing all 52 cards on the eight piles. Choosing which of several matching piles should receive a card is the only skill on offer. This one is hard: bad placements can't be undone, and only about 10% of games end in a win. It's played with a single deck, where chance outweighs skill.
Fans of this one will recognize Trusty Twelve Solitaire and Sir Tommy Solitaire.
The original, classic Solitaire is where this whole family of games started.

Enjoy playing!
8 tableau piles: Build up by rank regardless of suit, wrapping from King to Ace. Cards may only be played here from the waste, and once placed they never move again. Each pile is dealt one card face-up.
Stock: Click to flip over cards one at a time to the waste. There are two passes through the stock.
Waste: The top card is playable.
Eight tableau piles of one card each. Every card is dealt face-up.
The top card of the waste can be added to a tableau pile only if it's one rank higher than the pile's current top card, regardless of suit, so a 9 of any suit fits on any 8. The ranking is circular, so an Ace can be played on a King and a 2 on an Ace.
Cards already on the tableau may never be moved again — not to another pile, and there are no foundations to send them to.
Because cards never leave the tableau, the eight piles can never become empty.
There is one waste pile and the remaining 44 cards make up the stock.
When you click on the stock, one card from the stock is dealt to the waste. When the stock runs out, the waste is turned over to form a new stock; there are two passes in total.
The top card of the waste can be played to any tableau pile that will accept it.
The goal is to move the entire deck onto the eight tableau piles. If the stock and the waste are both empty, the game is won.
