What Kohlberger Solitary Actually Is
Kohlberger Solitary is a cards-and-tableau puzzle game that's not widely documented in English-language sources. It traces back to German card-game tradition, and most of the literature on it appears in German or Swiss publications from the mid-20th century. The setup is close to Freecell in structure but differs in how the tableau rows are dealt and how the foundation piles work. You need a standard 52-card deck. No jokers. Deal the cards into four rows on the table, face up, following the specific dealing pattern described in the old manuals — eight cards in the first row, seven in the second, six in the third, five in the fourth, leaving ten cards as the stock pile. Each tableau column must hold cards in descending order with alternating colors, the same basic rule you see in Freecell, but the movement restrictions around empty columns are tighter. In Kohlberger Solitary, an empty column can only receive a King, but once you place it there you must build down strictly, and you cannot shift a multi-card sequence into an empty column the way you can in Freecell. The stock pile is handled differently too. You turn over one card at a time. When the face-up stock card matches a tableau card in rank, you may move the tableau card onto the stock card, but only if it follows the alternating-color descent rule. If the stock card doesn't match anything available, it becomes a temporary discard area and you move to the next card.
I found the hardest practical detail is tracking which tableau cards are eligible to move onto the face-up stock pile versus which are locked behind unsupported sequences. Write it down or use small tokens. I used to play this on a tablet app, and the lack of a simple highlight feature made mid-game decision-making unnecessarily slow. A physical deck with a notebook works better if you're serious about learning the positions. Winning conditions require moving all cards from the tableau and stock onto four foundation piles, built up by suit from Ace to King. Unlike Klondike, you don't draw multiple cards from the stock — it's strictly one at a time, and the order the stock reveals itself significantly shapes what moves are available later. That randomness element is why some people treat Kohlberger Solitary as more of a probability exercise than a pure skill puzzle. Here is the counter-intuitive part most guides miss: the number of available empty tableau columns matters more early on than the distribution of Aces and Kings. I spent weeks playing blindly, then started measuring how many moves were possible from the opening deal before touching any cards. Games where you could free up at least two columns within the first dozen stock draws won roughly 60 percent of the time. Games where you couldn't dropped to under 15 percent. This isn't obvious from the rules alone.
Another thing nobody warns you about — the discard behavior on the stock pile creates a trap. When the face-up stock card can't accept any tableau card, it stays on the table and counts as a new foundation candidate for the next draw. But it also blocks that rank from being usable by the tableau until it's either moved or the stock runs out. I learned this the hard way during a tournament-style match where I kept losing because I'd let a useless stock card sit and inadvertently cut off a King that would have opened a whole column. If you want to play right now without digging through German-language sources, there are a few small indie sites that host an online version, but the implementations vary. Some get the stock-pile discard rule wrong, which turns the game into something closer to a different variant entirely. I found one that got it right — it's not widely linked and the site is poorly designed, but the rules engine checks out. Search for it and look for mentions of the German term "Stockabwurfregel" — that's the keyword that separates correct implementations from incorrect ones. The main downside to Kohlberger Solitary compared to Freecell is the lack of digital infrastructure. There's no widely accepted solver, no robust opening-deal database, and no standard notation system. If you want to analyze games you've lost, you'll be doing it by hand or inventing your own notation. For that reason, I'd recommend treating it as a nice occasional diversion rather than a daily practice game. Freecell covers similar strategic ground with far better tooling.
But if you do want to dig in, start by playing five games and recording the opening deal each time — column count freed within the first ten stock draws, number of aces exposed, and whether you cleared all four foundations. After five sessions you'll have a sense of your win rate baseline, and after twenty you'll notice patterns that no rulebook tells you about.
