Nice, but not tamper-proof.

Pick a 3 or 4 digit number - I take: 7401.
Jumble up the digits - I take: 0147 they don't say the number can't start with a 0 ...
Subtract the smaller number from the bigger one - okay: 7401 - 147 = 7354.
Circle one digit from the result, but not a 0 - I take: 4
Type in the remaining digits - okay: 735.

It then concludes that I circled a 3.

Close, but no cigar.

Luis, that's Groucho Marx's line from a television quiz he hosted in the 1950s when contestants got the answer wrong (can't remember the name of the show). Of course, being Groucho, he had that big cigar between his teeth most of the time.

... and I'm surprised no-one picked up on my error: 7401 - 147 = 7354 is incorrect, it should be 7254.

If you type in 725, it does come up with 4 as the missing digit.

Still trying to find out the magic formula ...

Clue #1 must be that the last digit of the result of the subtraction is always one of the digits of the number.

From time to time I use to play golf game (I never play in real life) and one of the TV guys said "Close, but no cigar" when you miss the put close to the hole.
Now I know why.
