For a bigger group, party and bluffing games give teenagers and adults something to sink their teeth into. Titles such as The Traitors board game and card game, both available from The Happy Puzzle Company, lean on reading the room and second-guessing each other, which tends to spark the loudest laughs of the night. Keep one of these for when the whole family is together at Christmas or on a birthday.

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.
Brain teaser puzzles for adults come in a few broad styles. There are mechanical puzzles, such as interlocking metal or wooden pieces you have to take apart and put back together, logic puzzles that ask you to work out a single correct arrangement, and spatial puzzles where you fit shapes into a fixed space. Knowing which type someone enjoys makes it much easier to choose one they will actually sit down with.
