Pipes Sudoku

Pipes Sudoku is a calm, brain-bending logic puzzle: Sudoku's deduction meets the satisfaction of laying pipe. One continuous pipe must travel from the inlet to the outlet across the grid. The numbers along the top and left edges tell you exactly how many cells in each row and column carry pipe. From those counts alone you can deduce the entire route. Every puzzle has exactly one solution, reachable by pure logic. No guessing, ever. Drag pieces onto the board or tap to place them, mark your deductions with the X and ? notes, and watch the pipe pressurize when you solve it.
