What about checking if the tile of the same type has already been placed where the mouse is being clicked?

if selectedTile == placedTile:
    placedTile.remove()
elif selectedTile != placedTile:
    selectedTile.place()

so, I kind of did that. But the var name is dragging instead of held. when dragging is true, it didnt run the code of removing. Else, it checks and removes. But what happens is that it first puts the tile, and then removes it, with the same click... I thought the mousebuttondown was still on the event queue so I tried to clear it, also without succes...

Oh, I see. In this case, I would use a variable 'held' to indicate the
tile that is picked up. 'held' would be None if the no tile is held.

When a mouse down event is received, if there is a piece in 'held'
(held is not None), place it. If 'held' is None, then remove the tile
at the mouse location.
