I'm trying to make puzzles with fewer constraints that are still fun to play. This is my latest attempt. As always, feedback is welcomed and encouraged, so let me know how I did in the comments below.

  • Normal Sudoku Rules: Fill each row, column, and 3x3 box with the digits 1-9 once each.
  • Killer Cages: Digits in cages must not repeat and must sum to the number in the upper left corner of the cage (if present).
  • Palindrome Lines: Digits along a gray palindrome line must read the same forwards and backwards in either direction.

Solution code: Row 5 from left to right.

Definitely solvable for beginners. But it would help you don't miscolour the pair of cells and end up with two paired cells in the same box. (˶ˆᗜˆ˵)

Entertaining solution path. Some experienced solvers will enjoy certain shortcuts but should remain solvable for most newer players.
