PUZZLE NO. 72 : Three Lines Sudoku

This is a practice puzzle for Sudoku GP ( Indian Round ) to be held this weekend. I am co-authoring this round along with Gaurav K. Jain, Hemant Malani, R. Kumaresan, Rakesh Rai, Pranav Kamesh & Prasanna Venkatesh Seshadri.


RULES : Classic sudoku rules apply. In each group of three lines :
  • One will follow Arrow Sudoku rules. The digit placed in a cell with a circle must be the sum of the digits placed in the cells that the adjoining arrow passes through. Digits may repeat on arrows. It is up to the solver to determine which end has the circle.
  • One will follow Thermo Sudoku rules. Starting at the bulb, digits placed along the thermometer must form a strictly increasing sequence. It is up to the solver to determine which end has the bulb.
  • One will follow Palindrome Sudoku rules. Digits along the line read the same in both directions.
         It is allowed that a line has properties of both Arrow and Thermo Sudoku ( for instance : 1-2-3-6 ).
