Once you understand the "rules" of how to tackle our Island and Bridges (or "hashi") puzzles, they are straightforward to do - just requiring logic and a bit of patience to work them out. We love these puzzles and hope that you do too.
Islands and Bridges Puzzles
NEW! Islands and Bridges puzzles are also known as "hashi" puzzles or just "bridges". They are a logic puzzle so children will need to put their thinking caps on, but once you've learned the rules they are quite straightforward to do - and very addictive! We love doing them, so decided to create the child-friendly version you see below. Scroll down to find out more about Islands and Bridges Puzzles and read how to do them online, or jump straight to the printables.
Printable puzzles in colour and black and white
All our Islands and Bridges puzzles come as printable pdfs. Each pdf is a set of 4 puzzles - because doing 1 just isn't enough! Each set comes in colour (best for kids) and black and white (best for adults). You can also download solutions for each set, also in colour and black and white. We've kept the solutions as a separate pdf so as not to tempt you to peek too soon!
What do I need to do the puzzles?
You will need a pencil and a rubber (eraser). If you are using the colour puzzles with children, you might want to laminate the pages or place them inside a plastic sleeve and use a dry-wipe pen to complete them. They are a great way to keep kids busy on journeys, rainy afternoons etc - and if you do them this way you can use the same puzzles over and over again.
Sets 1 to 5 are the easiest puzzles. Sets 6-10 will be slightly more challenging.Sets 11-15 will be more challenging still. And so on. We suggest that Sets 1 to 5 are suitable for children from around the age of 8, although younger children may enjoy tackling the puzzles once they understand the rules.
How to do Islands and Bridges Puzzles
Connect the islands (the circles) by drawing bridges between them according to the following rules:
1. Bridges must travel between two islands in straight lines.
This is allowed:
This is not allowed!
2. Bridges must not cross other bridges or islands.
This is allowed:
This is not allowed!
3. There can be no more than 2 bridges between a pair of islands.
Two bridges are allowed:
Three bridges are not!
4. Bridges can only run horizontally or vertically.
These bridges are allowed:
This diagonal bridge is not allowed!
5. The number of bridges to and from each island must match the number on the island.
If you count the number of bridges from each island, they will match the number on the island, like this:
These numbers don't match!
6. When all the bridges are drawn, you must be able to travel between all the islands.
Here is a hint: start by looking for the islands that only have one bridge. In this example, there is only one place that the bridge can go.
