Saw this in game analysis. Need a simple explanation
A blunder is a move that changes the game from Winning/Even to a losing position.
A mistake is a move that changes the game from Winning/Even to a worse but not losing position.

I believe its just a matter of magnitude @Majaivane
Mistake= that was a tiny bit careless
Blunder= Aarrghhh!!

It has to do with the change in evaluation. "Blunder" doesn't necessarily mean going from a winning position to a losing position, e.g. if SF says your eval is +9 and all out of a sudden after your move it goes down to +2, then technically you are still "winning", but SF will qualify your move as a "blunder", but as always Internet has the answer: lichess.org/forum/general-chess-discussion/what-are-the-differences#5
It‘s raw mathematics here on lichess.
Delta (your move) - (best engine move) determines the classification.
So being a queen up in a horrendous complicated position and simplifying to an easy rook-up situation can be considered a blunder.

A blunder is ??
A mistake is ?
A dubious move is ?!
An interesting move is !?

Once again: here it is just number crunching: a blunder (-5 to -2) can be „!“ (practically best move)
There isn't one. The whole business is fraught with misnomers, brought on by attempting to give some sort of "chess commentator" spin to what is purely numerical analysis.
You are better off concentrating on the numbers only.
Better yet, concentrate on the computer's alternate lines. :)

A mistake (?) either changes a drawn position to a lost position or a won position to a drawn position.
A blunder (??) changes a won position to a lost position.
All the numbers are just an approximation to that.
