One from each type
In each type, the game whose developer described it in the most detail. That is the whole selection rule. It is not a review.

Match-3

Mahjong

The eight types of puzzle
What this site is
PuzzleMoss collects free puzzle games that run in a web browser. They come from GameMonetize, a distributor that licenses HTML5 games from the people who make them so that sites like this one can embed them. The games belong to their developers. What belongs to us is the choosing, and the writing on every page.
The choosing is strict. When the site was built, the source catalogue held a little over 31,000 games. Roughly one in five was a puzzle, and a good share of those were knock-offs of famous games, aimed at toddlers, or the same game relisted under a fresh name. Those went first, leaving fewer than one game in twenty from the original catalogue. A game only made it onto the site if its developer had described it well enough for us to write at least 250 true, specific words about it. Where we could not, the game is not here, however good it might be.
How the puzzles are grouped
Most sites lump puzzles into one long list. We split them by what your head is doing while you play, because that, more than the theme or the art, decides whether a game suits you at a given moment.
Sort & Organise games ask you to put things where they belong: coloured water into tubes, nuts onto bolts, goods onto shelves. Match-3 and Mahjong & Tile Match are both about spotting sets, one by swapping pieces on a grid, the other by clearing tiles from a layout. Connect & Draw covers puzzles where you draw the answer, a pipe route or a single line through every dot. Block Puzzles are about space: fitting shapes onto a board and clearing rows before it fills up. Merge Puzzles build upwards, two small things becoming one bigger one. Brain & Numbers holds the pencil-and-paper end of things: sudoku, sums, logic grids and word games. And Hidden Object & Spot the Difference is simply about looking closely.
Finding one that suits your mood
If you want something for your hands while your mind wanders, start with sorting or merging. Both work in small, repeatable moves, so they are easy to pick up and easy to leave.
If you want to concentrate properly, try a sudoku or a logic grid, or a mahjong layout where every pair you take away changes what can be reached next. Block puzzles and match-3 suit five spare minutes: rounds are short and you find out quickly how you did. If you would rather look than reason, a hidden object scene asks for attention more than cleverness.
Every game page says how the game is played, which controls its developer lists, and whether the game is laid out for a wide screen or a tall one, which matters on a phone. Games load only when you press Play. Until then, nothing is fetched from the game provider at all.
