Piece count is the first thing to settle when you choose a jigsaw. Puzzles for young children usually have large pieces and a low count, so small hands can manage them, while 500 and 1,000-piece puzzles suit older children and adults who want a longer sit-down. If you are buying for someone new to jigsaws, it is better to start lower and work up than to hand over a 2,000-piece puzzle that never gets finished.

If you like the Genius Square, the same Happy Puzzle Co idea runs through a small family of games. Genius Star adds a bonus mechanic and a different set of pieces, Genius Gems and Genius Connection change the shapes and the goal, and Bee Genius is pitched at younger children who are new to shape puzzles. Each one keeps the roll-and-fill pattern while giving you a fresh challenge.

The Genius Square has become a favourite for families and solo puzzlers who want a game that sets up in seconds and plays differently every time. You roll the seven dice, place a blocker on each grid square the dice point to, then fit the nine coloured shapes into the space that is left. There is always at least one solution, and often more than one, so nobody gets stuck on an impossible board.

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.

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 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.
