Logic Masters Deutschland e.V.

On August 10th-11th 2024, 16 twitch streamers participated in a 48 hour sudoku stream raid train, organized by the wonderful Ratfinkz! Information about the participating streamers and the event as a whole can be found here. This puzzle was made to commemorate the event. Finkz the Rat was used with permission from Marty Sears, and was not harmed during the making of this puzzle.

• After months of captivity as a laboratory test subject, Finkz the rat has escaped and has started her own railroad company! Her aptitude at navigating mazes should prove useful in her new project: building a train line that can run from Nellville to Carabet City in just 48 hours, stopping at 16 Streamer Stations along the way!
• Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
• Draw a train route in the grid that starts at one station, ends at a different station, and visits all other stations along the way. The train route may only move orthogonally, and may not touch itself, even diagonally.
• The final route must be a valid 16-line, meaning the entire route can be broken into segments where each segment sums to 16.
• A digit in a station represents the number of stations that contain that digit. Additionally, that digit counts the number of cells on the route that can be seen vertically and horizontally from that cell, including itself. A cell not on the route blocks the line of sight.
• Digits in a cage do not repeat and sum to the total in the top left corner.
