PUZZLE NO 329 : THERMO - LITTLE KILLER - SUM SANDWICH - X SUMS HYBRID SUDOKU

 A TRIBUTE TO THE LEGEND ROGER FEDERER

Today's Sudoku is a tribute to the greatest - Roger Federer. He announced his retirement from tennis yesterday. With age already having caught up and his body not in full shape, he decided to call it a day. With his retirement, he has left a void, which will be very difficult to fill. He was the most graceful and the most talented of all the tennis players. He finished his career with 20 grand slams and 28 masters 1000. We will always miss his grace, his effortlessness on the court, his one handed backhand shots, his drop shots, him marching towards the net and winning points. His numbers may have been overshadowed by his contemporaries, but his legacy will live on forever.
