Slower, more thoughtful word games suit older children and adults who like to plan a high-scoring play. These reward a wider vocabulary and a bit of tactics, so they are better kept for players who enjoy taking their time. If you are buying for a mixed-age family, a fast game is usually the safer bet, since it keeps the youngest involved rather than left behind.

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 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.
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.
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.
