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.

Matching a game to a child''s age saves a lot of guesswork. For four and five-year-olds, look for chunky, simple games with clear rules and short rounds, so there is not much waiting between turns. Bee Genius, pitched at younger children, is one example that uses big pieces and a single, easy-to-grasp goal.

Stocking fillers are where the smaller puzzles shine. Self-contained games such as the Genius Square, along with pocket brain teasers, drop neatly into a stocking and give someone a challenge for happypuzzle.co.uk the quiet bit of the morning. For children, a game matched to their age, from Bee Genius for the little ones to WordSnap XL for older siblings, tends to get more play than yet another plastic toy.

Think about space and time too. A large jigsaw needs a table or board where it can stay out for days, which is not always practical. Puzzles can be a calming, screen-free way to spend a wet afternoon, and working on one together is a quiet way for a family to sit down side by side without a fixed finish time.

For the big family session, party and bluffing games carry the day. The Traitors board game and card game, both available from The Happy Puzzle Company, work well with a larger group because they turn on reading each other and keeping a straight face, which suits the after-dinner mood. Keep one of these back for the moment when everyone is round the table and looking for something to do together.

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.
