Theme: Polka Dots
Author/Opus: This is the 88th puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.
Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). If a black circle is given between two adjacent cells, then the two numbers must have a ratio of 2. Pairs of cells without circles can have any relationship. Also, some thermometer shapes are in the grid; numbers must be strictly increasing from the round bulb to the flat end.
