Difficulty is worth checking before you buy. A puzzle that is too easy gets solved once and put away, while one that is far too hard can end up back in the box. Many puzzles carry a difficulty rating, and it helps to match that to how much time the person likes to spend. Someone who wants a ten-minute coffee-break challenge needs something different from a person Happy Puzzle to pick away at the same puzzle over several evenings.

Difficulty varies a lot, so read the age guidance and the suggested group size. A game aimed at families with younger children keeps the clues fairer and the reading lighter, while a harder title will have adults scratching their heads. Working through the puzzles together is good fun, and there is a real sense of satisfaction when the last lock clicks open.

For gift ideas sorted by age band, with the number of players and rough playing time listed for each, browse the games-by-age pages at family board games.

From about six upwards, children can handle puzzles with a bit more thinking. The Genius Square and Genius Star ask them to roll dice and fit shapes into a grid, which keeps them busy without needing anyone to read a long rulebook. Games like these also work solo, which is useful for a quiet half-hour or a long car journey.

The image matters as much as the count. Scenes with plenty of variety, such as busy street scenes or landscapes with lots of colour, give you clear areas to work on and tend to feel achievable. Puzzles that are all one colour, or that repeat a pattern, are far harder because you cannot rely on the picture, so save those for someone who likes a proper challenge.
