About This Game

Game Introduction

Code Duel: Logic Puzzle Game is a digital tabletop experience designed for two players. It is a pure test of strategic foresight and analytical thinking. Every clue is a piece of a larger puzzle. The premise is simple: each player creates a secret 4-digit code where the sum of all digits equals 20. Then, players take turns deducing the opponent's code. This constraint creates a vast but defined space of possibilities. Victory is earned through careful observation, logical inference, and clever misdirection.

How to Play

To play, both players confidentially input their personal 4-digit code, ensuring the total is 20. Gameplay proceeds in alternating turns. On your turn, you receive a clue based on your latest guess, revealing information about digit placement and values. You must interpret the clue, cross-reference it with previous data, and eliminate impossible combinations. Then, based on your analysis, submit your best guess for the opponent's full code. A correct guess ends the game in your triumph.
