Here are hundreds of free Bridges puzzles suitable for printing. In Japan, Bridges are known as Hashiwokakero (Japanese: 橋をかけろ). They are also known as Hashi or Chopsticks. In these puzzles, you connect the islands to form a network so that you can reach any island from any other island. The number on each island indicates the number of outgoing bridges. You may only connect islands horizontally or vertically, and you may use one or two bridges to connect islands, but no more than two. Each Bridge puzzle has only one unique solution, which you can find without guessing.

The puzzles in these books get progressively harder as the book numbers get higher.

A pentomino is a shape made up of five smaller squares. There are 12 differently-shaped pentominoes in total.

You can use pentominoes to create many different shapes. Here you can see a symmetric butterfly made of all 12 pentominoes:

Now it's your turn. Can you place all twelve pentominoes inside this outline of an elephant? Remember that the pentominoes are not allowed to overlap, there shouldn't be any gaps, and shapes should stick out of the body of the elephant:

Here is another example - a pentomino dinosaur:

Since April 2020, I have been supplying Star Battle puzzles to the New York Times, where they are being published as 'Two Not Touch'. You'll find many more of these delightful puzzles, in 1-Star, 2-Star and 3-Star varieties, here on my website on the Printable Star Battle page. I also carry Interactive Star Battle puzzles which work nicely on phones and tablets. Warning: These puzzles are very addictive!

Every day from Monday thru Saturday, the Times publishes an easy puzzle, and a medium-difficulty puzzle. These correspond to book numbers 1-35 in my collections (which increase in difficulty from book 1 to book 100). Those higher book numbers contain significantly more challenging puzzles.

If you are new to this puzzle, you may find this introductory tutorial helpful.

If you can already solve the easiest ones, but are struggling with harder puzzles, check out my intermediate tutorial.

Finally here is my advanced tutorial, which covers a number of useful rules-of-thumb for solving these puzzles. Enjoy the puzzles!
