Tag 16 - Hashiwokakero

(Published on 3. February 2021, 22:38 by CJK)

In December 2020 there was a logic puzzle advent calender on mathebau.rocks. These puzzles will be uploaded to the puzzle portal in the next weeks.

16. Dezember - Hashiwokakero

Rules: Connect the circles with bridges, such that every circle is reachable from every other. Bridges are build horizontally or vertically and cannot cross each other or go over other circles. Between two circles, there are at most two bridges. A number on a circle indicates how many outgoing bridges from this circle are there alltogether.

Link for online solving

Solution code: For each column (left to right) the number of vertical double bridges (each double bridge counts as 1). Skip columns without vertical double bridges (i.e. do not enter zeros)

Hab den Lösungscode 10 mal falsch eingegeben, weil eine fiese Doppelbrücke sehr kurz ist...

@ManuH: Spalten ohne Doppelbrücken sind beim Lösungscode zu ignorieren, keine 0 verwenden.

Was bedeutet "Überspringe die Spalten ohne senkrechte Doppelbrücken? Keine Nullen eingeben?

Excuse me: Is the vertical single bridge (no bridge) replaced by 0? Double bridges are counted as "1" or "2", thank you!

@cdwg2000: Double bridges are counted as 1, and you can ignore all single bridges for the solution code. Also, you can ignore all columns without any double bridge (i.e. not enter 0s)
