What is Ninedex?
An overview of the game and its features.

About the Game

Ninedex is an unofficial, fan-made digital adaptation of the brilliant Japanese strategic card game, "Double Nine" (ダブルナイン). The goal is simple: have the highest score when the game ends.

Each player has a board with two columns: a Tens Place and a Ones Place. On your turn, you draw up to two cards and play one, placing it on either column to form your score. The real strategy lies in the cards themselves. Each card has a unique, powerful effect that can turn the tide of the game—from stealing your opponent's cards and swapping entire boards to protecting yourself from attacks. The game ends when the draw pile is empty, and the player with the highest score wins.
