Give correct hints for a code lock with repeated digits and slow down guessing

With a code that has the same digit twice, the usual hint counts a digit as both in place and misplaced, and the player is led astray. Here is the right way to score each guess, plus a waiting time that grows with wrong tries and ends on success.

Why this works

A hint must say something true about the secret as a whole, and a repeated digit can only be matched as many times as it really occurs there. Counting what each side holds, then removing the exact hits, gives a hint that never overstates, so the player can reason from it.

When not to use it

Skip the waiting time when the lock is a story puzzle that must stay friendly, or when guessing is already limited another way, such as a few tries. Skip the detailed hints when the lock is meant to be solved from clues in the world.
