It is worth thinking about the setting too. Games with a drawstring bag or a tin survive being thrown in a rucksack better than a large flat box. For a caravan or a beach hut with limited space, pick a few small games rather than one big one, so you can match the game to the mood without taking up a whole shelf.
By eight to twelve, most children enjoy games with a little strategy or a competitive edge. Word and number games, such as WordSnap XL, and family favourites like Snakes and Ladders in its bigger 3D versions give them something to plan around and enjoy together. Mixed-age families get on best with games that scale, so older and younger siblings can play the same round.
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 to pick away at the same puzzle over several evenings.
To compare escape room games by difficulty and player count, and find one that suits your group, see the escape room range at jigsaw puzzles and games.
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.
Brain teasers can help pass the time on a commute or wind down at the end of the day, and they make a good talking point left out on a table. They are also handy gifts because they do not need batteries, a screen or another player. A well-made puzzle in solid metal or wood also tends to last, so it can be handed round the family for years.
