xAxB Decoder

Use logic to crack digital passwords and become the ultimate decoder!

Welcome to the reasoning world of xAxB Decoder, a multi-digit guessing game that combines strategy, logic and patience. Here, you face not only a hidden number combination, but also a password puzzle that needs careful analysis.
At the beginning of the game, the system will generate a secret code with a specified length (such as 4 or 5 digits) and no duplicate numbers. Your task is to gradually approach the truth through continuous guessing and combining with the "xAxB" prompt fed back by the system: "A" means that the number and position are completely correct, and "B" means that the number exists but the position is wrong. For example, "2A1B" means that two numbers are in accurate positions, and another number exists but is misplaced.
Every guess is a logical deduction: eliminate impossible combinations, lock potential candidates, and finally crack the complete sequence in the least number of steps. There is no luck, only clear thinking and efficient strategies.
XAxB Decoder has a simple interface, clear feedback, and supports a variety of digit difficulty choices, which is suitable for all kinds of players from novices to hardcore logic enthusiasts. Whether you want to exercise your brain, kill time, or relive the classic "Bulls and Cows" game, this game can bring pure and profound fun to solve puzzles.
