Games for 1 player
Can you recommend some games that a person can play by themselves?
Dexterity Games suitable for a single player
Apart from Solitaire, there are some traditional games that are suitable for a single player - generally because one player is at the table at any one time and the objective is to gain the most points. Therefore, some reward can be gained by practising and trying aiming to improve one's "personal best" score.This list does not include games like Alley Skittles and Aunt Sally which would otherwise apply - because you need someone at the other end to keep resetting the equipment.
Most puzzles are solitary affairs, including Solitaire.
PuzzlesThere is an also enormous category of card games called "Patience" all of which are for one player - and many of these are most enjoyable and/or engagingly frustrating. There is even a version of Cribbage for one player. There are some board games that are popular and complex enough that setting puzzles or challenges in that game for a person to try has become de rigeur. For example, Chess, Go, Bridge and Scrabble are all games for which puzzles can be found in books and in the national press on a daily basis and these are excellent ways to hone your skills.
Solo Mind Games
Of the 'mind games', choices that are truly suitable for one player only are limited. If you would like to sit down with a game designed for multiple players that is entirely or mostly down to skill such as Chess, Halma or Scrabble and play the game by yourself in the same way, it usually just doesn't work because you always know the move the other player is likely to make and what's in their mind! The same is true of most card and domino games because the challenge is not knowing what is in the other player's hands.
