Normal sudoku rules apply. The circled numbers are the sum of numbers along the attached arrows.
Any three consecutive cells in any one row contain exactly one of 1,2,3, one of 4,5,6 and one of 7,8,9. Any three consecutive cells in any one column contain exactly one of 1,4,7, one of 2,5,8 and one of 3,6,9.

This is a clever twist — starting from just 25 givens and letting the consecutive-cell groups do so much of the work makes the solve feel far more elegant than the sparse grid suggests. The arrow sums are a nice extra layer on top. For a lighter daily challenge I usually warm up with a word puzzle and check Today's Octordle Answer afterwards, but this Sudoku is a much meatier puzzle to sink into.
