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.

Christmas is when board games and puzzles earn their keep. With the family together and a stretch of quiet days, a good game gets everyone off their phones and round the table, from the youngest cousin to the grandparents. The trick is having a mix ready: a quick game for the afternoon lull, a party game for the evening and a puzzle for someone who wants a quiet corner.

If you like the Genius Square, the same puzzle 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.

Word games sit in a sweet spot between fun and family-friendly. They give players a reason to think about letters and words, but wrapped up in a race or a Happy Puzzle rather than a test. That makes them a popular choice for families who want screen-free play that keeps everyone reaching for letters at the same time.
