The Lock open

Challenge yourself to decode the sequence as swiftly as possible.

You have the option to select different code lengths to vary the difficulty.

Each attempt will provide a hint indicating your proximity to the correct solution, enhancing your strategic approach.

Begin practicing with a code length of 3 before attempting more complex challenges.

This game bears similarities to Mastermind but utilizes digits instead of colored pegs, offering a numeric twist on classic logic puzzles.

Symbol explanations:

• 'v' — signifies a correctly guessed digit in the correct position.
• '+' — indicates a correct digit in an incorrect position.
• -' — denotes an incorrect digit.

Note: These symbols represent the status of guessed digits, not the actual digits themselves.

For example, given the code 335:

• 123 → (+ --)
• 355 → (v + -)
• 335 → (v v v)
