(#5273645) Re: Four Coins: Another puzzle of 12 coins
Posted by Jools on 26 Aug 2021 at 10:45AM
yes I had thought of 3x 4 coins, but I thought it would take 2x tries to find the group with the fake coin.
But had a rethink. I can do it if they initially balance, but if they don't it takes an extra try
Still figuring out that bit
