A strategic number-guessing game combining Hit & Blow with bluffing
A strategic deduction game where you guess the secret number (Master Number). Players take turns guessing, racing to be the first to figure it out. Similar to Hit & Blow or Numeron, but with a twist: each player is given one correct digit at the start (an "Open Number"), creating information asymmetry. The skill is when to reveal your Open Number, and reading what others know.
Since the first correct answer wins, earlier turns are advantageous. It's recommended to start with the youngest player or the previous loser.
If Open Number is enabled, each player learns 1 correct digit. Players take turns answering in the chosen order.
When your turn comes, number input buttons appear at the bottom. Reason out the Master Number and submit within 60 seconds. The log shows Hit and Blow counts. Hit: correct digit in the correct position. Blow: correct digit in the wrong position.
The first player to correctly submit the Master Number wins, and the game ends.
Dokopa offers fine-grained rule customization.

Think about where others' Open Numbers might be while you answer
Master Number: a number of any number of digits, with no repeated digits. "3302" doesn't qualify; "7290" does. Numbers can also begin with 0, like "08341".
Master Number: 01234 / Guess: 02468 → Hit: 1 (the leading 0 matches), Blow: 2 (2 and 4 exist but in the wrong positions)
