I built a free browser game where every puzzle revolves around deducing a hidden six-digit code from a set of clues.

A thru F are unique integers from 1-10.

The puzzles are generated with a single valid solution and are intended to be solved entirely through logic. No login, no downloads, and no signup required.

I'd love to hear from puzzle gamers:

• How difficult was it?
• Did the clue system make sense?
• Did you enjoy the deduction process?

A–F are unique integers from 1–10.

Post your solve times and strategies.

• Unlimited Random Puzzle generation
• No account needed.

These puzzles are tiered by the total number of remaining values for all variables (A thru F) once all "Standard Deductions" have been applied (i.e. eliminations that don't require clue-combos).

All feedback is greatly appreciated.

Goal:
Assign six different values from 1–10 to the variables A–F, using the clues provided.

The Key Challenge:

Try to solve it through a forced logical path, not by brute-force guess-and-check.

As always, there is exactly one solution.

Note: All six clues are required in order to determine the value of any letter.

Good luck. 🙂
