Clear out as much the top and bottom rows and leave the middle row untouched. Once you’re at the middle row start with the two matching pairs in the middle and keep gap. The key is to play the top magnetic piece as soon as you have the gap from getting rid of the N. Only one chance to shoot the gap so be careful. Then easy after that move

The key is use the top tile from the 3rd column from the right and match it with the 2 second tile from the bottom of the first column from the right. Get rid of the big cluster tiles in Column 4 from the right. March the top tile in column 2 (from the right side) and match with top tile in column 5. Then match the rest of the paired tiles in columns 4 and 3

The key is use the top tile from the 3 column from the right and match it with the 2 second from the bottom of the first column from the right. Good luck
