Daily Between Lines Sudoku
The extra rule
Digits on a line lie strictly between the two circled ends.
If the circles hold 2 and 8, everything on the line between them is somewhere from 3 to 7. The ends can be either way round, low to high or high to low.
Long lines are the ones to read first. A line with four cells between its circles needs a gap of at least five between the ends, which usually forces a 1 or a 9 into one of them.

Solvable Without Guessing
Every puzzle here was generated and then handed to a solver that is only allowed techniques a person can use. If it could not finish the grid without a guess, the puzzle was thrown away rather than published. That also makes the answer unique, because every digit it placed was forced.
