Tabletop games can be classified according to the general form, or equipment utilized:^[3]

Games like chess and draughts are examples of games belonging to the board game category. Other games, however, use various attributes and cannot be classified unambiguously (e.g. Monopoly and many modern eurogames utilize a board as well as dice and cards).

For several of these categories there are sub-categories and even sub-sub-categories or genres. For instance, German-style board games, board wargames, and roll-and-move games are all types of board games that differ markedly in style and general interest.

The various specialized parts, pieces, and tools used for playing tabletop games may include:

• Stopwatch, clock, hourglass or egg timer
• Meeples, Miniature figures, pawn, or playing piece
• Gambling chips or play money
• Game board
• Game box or container
• Scoreboard or paper pad
• Cardboard Counter, Dial Counter, Marker or peg for keeping score/tally
• Pencil
• Rule manuals
• Ruler or measuring device
• Modelling clay
• Gamemaster's screen
• Bowls, trays, or component organizers
• Stickers often used in Legacy games
• Card sleeves used in games that have a "Card Crafting System"^[4]
• Randomizers such as:
  • Coins
  • Dice, which can include polyhedral dice
  • Dice tower or Dice cup
  • Playing cards, which can be collectible cards
  • Shuffling machine
  • Tiles
  • Tops, such as Teetotums or Dreidels
  • Drawstring bag
  • Spinners
  • Bones, Cowrie Shells, or Stick dice, used in ancient games

A refereed game could also include various aids to play, including scenario packs and computer game aids. Role-playing games can include campaign settings and various supplementary manuals and notes.

As an alternative to classifying games by equipment, they can also be classified according to the elements of chance involved. In game theory, two fundamentally different elements of chance can play a role:

• Chance due to outcome uncertainty, e.g. due to dice rolls or due to unknown cards being dealt during the game. Games in which outcome uncertainty plays a role are referred to as stochastic games as opposed to deterministic games.
• Chance due to state uncertainty, e.g. due to the opponent's position or cards not being visible, or due to the simultaneous move character of the game. Games in which state uncertainty plays a role are referred to as partial or imperfect information games as opposed to full or perfect information games.

Examples of the chance classification for some well-known tabletop games are given in the table below.
