Theme: Cage Symmetry and Logic (contributed by GMPuzzles to the Indian Puzzle Championship)

Author/Opus: This is the 181st puzzle from Thomas Snyder, aka Dr. Sudoku.

Rules: Variation of TomTom rules. The letters A through J represent different digits from 0 to 9.

Answer String: Enter the 3rd row from left to right followed by the 5th row from left to right. Separate all rows with a comma. Use digits (and not the letters A-F) for entry.

This is a “Twisted Tuesday” puzzle variation.

Theme: Cage symmetry and repeated clue values

Rules: Variation of standard TomTom rules. The indicated range [1-6] is larger than usual for a 4 x 4 puzzle. Some cells containing slashes require two digits to be placed. These cells should be treated as fractional values (top value over bottom value) for the purposes of solving the puzzle.

Answer String: Enter the 3rd row from left to right, followed by a comma, followed by the 4th row from left to right. (Note: for the cells with slashes, enter the top before the bottom.)
