Welcome back! This month marks the one-year anniversary of my puzzle blog; I hope you’ve enjoyed all the different types of puzzles I’ve thrown your way so far. Also, if you’ve been following my Detective Watts series, keep your eyes peeled for a development coming very soon. I’m beyond excited to share it with you, and thanks for your patience until then.

To start this puzzle cycle fresh, I present you with another hashiwokakero (“Bridges”) puzzle. As a reminder, your goal is to connect all the flasks on the grid with tubes that meet the following criteria:

• Tubes must begin/end at distinct flasks and travel straight between them. Tubes cannot run diagonally, and they cannot cross any other tubes or flasks.
• The number on each flask indicates how many tubes must be connected to it.
• You cannot connect more than two tubes between a pair of flasks.
• The tubes must connect the flasks into a single group.

The pictures below depict a sample puzzle on a 5×5 grid, along with its solution. The tubes are drawn with yellow lines between the flasks.

Now, can you solve the puzzle below and help Jasmine complete her next experiment?

The solution will be released in the next blog post. Also, if you tried the puzzle from the last blog entry, here is its solution below. I hope you had fun pairing up all the students!
