The whole catalogue sits below, split into the shapes this genre actually comes in. Two of them are rules — stacked solitaire, where tiles cover each other, and flat connect, where a path of at most two turns joins a pair. The rest are variations on those two: towers that pile the stack higher, cubes you rotate, boards drawn for touch, sets with holiday artwork, and the Flash-era titles kept alive through an emulator.
A board that genuinely belongs in two sections appears in both. A connect grid with Christmas tiles is filed under connect and under Christmas, because someone looking for either would expect to find it there.
If you are not sure where to start: solitaire is the classic and the slowest, connect is the quickest to learn, and the top section holds whatever has kept people coming back for years.
Each section below shows a dozen of its boards; the link under the row opens the section in full. Every board has a page explaining what it asks of you before you spend twenty minutes on it.
