Let's Build Bridges

Let's Build Bridges is a collection of logic puzzles, also known as Hashi, Bridges, or Chopsticks. The goal of each puzzle is to connect all the "islands" by drawing a series of "bridges" between them. The rules are:

* Bridges must start and end at an island
* Bridges can only be drawn in straight lines (no diagonal)
* Bridges cannot cross each other
* At most, two bridges can be drawn between islands
* The number of bridges connected to each island must match the number on the island
* The bridges must connect _all_ the islands in a single, contiguous group

The first few puzzles are easy, but watch out, as the difficulty ramps up quickly! There are 100 puzzles to solve. Have fun building bridges!
