What’s New Version 2.3

Refining the game for a smoother player experience.

Description

Feeling overwhelmed by a busy schedule? Take a short break and enjoy a classic logic challenge. 1A2B offers a simple yet engaging puzzle experience that fits perfectly into your daily routine. This game follows the well-known Cows and Bulls rules. Enter a series of digits, and the game will reveal how many Bulls (A) and Cows (B) you have. Bulls indicate correct digits in the correct positions, while Cows represent correct digits in the wrong positions. The two do not overlap. For example, if you try “1234” and receive 2A 0B, it means two digits are correct and in the right place. If another guess like “1564” returns 1A 2B, it means one digit is correctly placed, while two others appear in the target answer but in different positions. Game modes: 1. Guess a 4-digit non-repeating number in 8 attempts. 2. Guess a 4-digit non-repeating number in 10 attempts. 3. Guess a 5-digit non-repeating number in 12 attempts. Challenge yourself or compete with friends, and enjoy a refreshing mental workout. If you have any questions, feel free to contact us at miaozhi.ai@gmail.com.
