Minigames are the two player-versus-player board games built into MapleStory Classic World: Omok and Match Cards. Either can be set up anywhere a player can stand, and other players join by walking up and clicking.
Both run through the same room system. A room can be public or password-protected, both players signal ready before the game starts, and the client tracks turns, wins, losses and draws.
Omok
A five-in-a-row board game. Setting one up needs an Omok set, and the sets differ only in the shape of the playing pieces: six sets exist, covering every pairing of four piece shapes.
| Set | Pieces | |
|---|---|---|
 |
Slime & Mushroom Omok Set | Slime and Mushroom |
 |
Slime & Pig Omok Set | Slime and Pig |
 |
Slime & Octopus Omok Set | Slime and Octopus |
 |
Pig & Mushroom Omok Set | Pig and Mushroom |
 |
Octopus & Mushroom Omok Set | Octopus and Mushroom |
 |
Pig & Octopus Omok Set | Pig and Octopus |
Each set is made of an Omok Table plus the two piece types, and the pieces are purely cosmetic: a Slime piece plays exactly like a Pig piece.
Match Cards
A memory game played on a grid of face-down cards. It needs a Set of Match Cards to host, and the cards themselves are Monster Cards, described in game as something you "need to have plenty of".
The client carries three separate match effects for the game, so a successful pair is signalled differently depending on the situation.
Room controls
Both games share one set of controls, which the client draws as buttons around the board.
| Control | Purpose |
|---|---|
| Ready | signal you are set before the game begins |
| Start | begin once both players are ready |
| Enter | join a room |
| Ban | remove someone from a room you host |
| Forfeit | concede the game |
| Claim draw | offer or claim a draw |
| Undo | take back a move |
| Leave | exit the room |
A room shows its host's name, both players' names, the running score and whose turn it is. Rooms can be locked with a password, which is how private games between friends are arranged in a crowded market.
What the files do not settle
The client holds the board artwork, the piece shapes, the room controls and the win, lose and draw states. It does not hold the rules themselves, the board size, or whether anything is staked on the outcome, since all of that is handled by the server.
