Because it runs on luck rather than skill, the game levels the field across ages. A grandparent, a parent and a small child can all play the same round, and the youngest is just as likely to reach the top first. That makes it a reliable choice for family gatherings, and a gentle, low-pressure way to get the youngest players involved in a game night.
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.
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.
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.

The trick to a family game night that does not fall apart is picking games that work across ages. Younger children lose interest when a game runs too long, and older players switch off when the rules are too thin. A mix of one quick game, one party game and one slightly longer game usually keeps everyone at the table without anyone getting bored or overwhelmed.
