Most Neopian games can be found on the Games page, but there are a couple that don't fit into the regular catagories and can only be acessed through certain other methods (Alternative Games). However, these games are fairly rare, and in some cases have strict rules, (ie - you can only play Deadly Dice at 12:00 Neopets' time.) so this page will be focussed on those games that can be found on the games page.
Neopets has a wide variety of games available, catagorized into Action, Puzzles, and Luck/Chance. Many Neopets games are actually based on well known, previously existing games, such as Snake (Meerca Chase) or Asteroids (Nimo's Pond), while others are innovative ideas.
Each game is also assigned a difficulty level: Easy, Medium, or Hard, shown through a small star thumbnail beside the games. The difficulty ratings seem to refer to the challenge involved in playing them, rather than involved in earning neopoints from the game, as many of the games that are labled as Hard can actually have higher payouts than the "easier" games.
