Puzzle 33: Sackbahnhöfe

Saturday was the German Logic Masters in Stuttgart. I’m mostly happy with how it went, placing fifth after last year’s seventh in what was probably a stronger field. Though missing place four and thus the A-team for London by a single point is a bit hard.

The puzzles were great, I particularly enjoyed the “special” rounds, such as the Doppelter Rundweg or the final Vier Jahreszeiten. They’re available now as online contests.

I had a bit of time this year and made some puzzles in preparation that I’m going to post over the next couple of days. The first is a Sackbahnhöfe.


Rules (from the booklet) Draw a loop with some branches into the grid, which visits every field of the grid. The loop crosses itself only at the marked crossings. Fields with numbers are railway stations. The loop branches in the field before the railway station. There may be only one branch in a field. The branch then moves straight through the railway station, and ends in the field after it. The branches with the stations have to be in increasing order along the loop.

See the contest page for instructions that include an example.
