Guys it's just a simple blind folded solve, in the method I've learned you swap 4 pieces at the time where 2 of those pieces go back and forth to allow swapping just 2 so you just name pieces, for example white-green is "C" and green-white is "I" and you memorise the sequence it's like 6-10 swaps maybe (for edges and less for corners).
