Coins - Back to the Logic Problems
Imagine there are 3 coins on the table: gold, silver, and copper. If you make a truthful statement, you will get one coin. If you make a false statement, you will get nothing.
What sentence can guarantee you getting the gold coin?


Spoiler for Solution

Spoiler for old wording


Your "solution" is NOT accurate. You are missing the key word here: "GUARANTEE". Your sentence does NOT guarantee the gold coin. (If the "coingiver" planned on giving the sivler coin for the first truthful statement, then your sentence would be false. No guarantee.)

Now, here are the stipulations:
1. A truthful STATEMENT gets ONE COIN [undefined as to WHICH coin.]. (*There is no defined limit to the number of truthful statements.)
2. ONE sentence must GUARANTEE the gold coin.

Therefore, the answer is simple: One sentence, 3 truthful statements. You get all 3 coins, INCLUDING the gold. GUARANTEED!!

Example: "Our sun is a star, our Earth is a planet, and our moon orbits the Earth."

GUARANTEED.

"I will get no coins"

Assuming that every statement I make has a loophole and can be proven false, respond with a statement that complies with the inevitable answer.
