Original MONMONMON game

MONMONMON has two distinct card-game experiences. The original game lives at /gameboard, with practice at /gametime and multiplayer at /gameboardmulti. Hidden Feelings is the separate five-card secret-feeling game at /play. A strategy or API call for one game should not be presented as a rule of the other.

The original flow

Follow the brown status area and the pulsing next-action control. Shuffle the positive feelings to choose the round's feeling. Select one of the Monster's hidden cards to reveal its score, then choose your own card to compare scores in the same feeling. The higher feeling score wins the round. Continue using the board's prompts for ties, remaining cards and the final result. The board celebrates a player win with confetti.

Cards show their monster names and overall ratings in the printed artwork. The individual feeling values determine a round's comparison. The art is made from katakana parts: the head, body and foot combine to form the monster's name. Different monsters and color combinations give the collection its visual variety.

Practice and collections

Practice offers a way to learn the original interaction without first acquiring a collection. The collection explorer lets you inspect cards, flip them to read attributes, and filter by rarity, colors and the letters used in each monster. A digital collectible in a wallet is distinct from a free card shown for practice or preview. Free play does not mint or transfer cards.

The community leaderboard combines recorded Solo, Multiplayer and Hidden Feelings results. Colored game icons identify the games represented in a player's record. Rankings use recorded wallet games; collectible ownership alone does not create a ranked player. Guest results appear in recent activity without being pooled into one ranked guest identity.

Agent access

The original game's live browser interface is the supported way to play it. There is no documented original-game gameplay API or remote MCP move tool. Browser agents can read the visible prompts and operate the existing controls. WebMCP can open the original game and explain its rules. For a complete documented server-controlled gameplay interface, use Hidden Feelings instead.
