A man sits blindfolded at a table with 20 coins laid out in front of him. He does not know the layout of
the coins, only that ten are heads and ten are tails. He has a pair of gloves on and while he can feel
where the coins are, he can't feel whether they are heads or tails. His task is to create two groups of
coins, each having the same number of heads and tails. He may only move or flip coins. How can he
accomplish this (while remaining blindfolded)?
Do you have a suggestion
for this puzzle (e.g. something that should
be mentioned/clarified in the question or solution, bug, typo, etc.)?
