do 3 on one side and 3 on the other If they are equal, put 2 of the other 3 on the scale on opposite sides if thats equal, its the other coin if not, its the heavier one If the first weighing was unballanced, do basically what you would have done for them being equal, but with the 3 coins that made it heavier

Make 3 groups of 3 coins each, and weigh them If one side is heavier, take the 3 coins from the heavy side, and weigh 2 of them If one side is heavier again, than you know that's the heavy coin Otherwise it's the coin you didn't weigh If at the first attempt the scales remain equal, the coin is one of the 3 coins you didn't weigh So you weight two of those 3 and the process would be the same

Comment from : @misteriddle

stupid youtube comments i can't write it out, because there isn't enough room, and you cant draw it out, because the comment errors and tells me to try again either way, i got it and i appreciate the cool riddles
Comment from : @SneakySolidSnake

Glad you found it easy!
Comment from : @misteriddle

lol! Now the question is, which one is the 9th one?
Comment from : @misteriddle

Well He did say that the ninth one was heavier, so just keep track of the ninth one And that one will be heavier Trololol
Comment from : @mrdeadb0b

That won't ensure that you'll find the heavier coin
Comment from : @misteriddle

Erm The question is how do you find the heavier coin So just saying find the coin that is heavier won't be sufficient enough as a solution
Comment from : @misteriddle

find the coin that is heavier and take the lighter coin and try the other 7coins
Comment from : @nazaars

@xShadow125 The thing is, it has to be done in 2 moves, but if you put them in one by one, it could take up to 8 moves

@MrPoohbear2218 Let's say it does lean to one side, how would you know which coin it is from that pile of 4 coins?
Comment from : @misteriddle

you can do it with four coins eack as well put four on each side if it leans the the heavier side has the coin if it doesnt lean the coin left out is the coin you are looking for
Comment from : @MrPoohbear2218
