1 puzzle, all different.

Bridges

Join the circles with straight lines, across or down, so each circle touches as many lines as its number. Use one or two lines between a pair, never cross another line, and link every circle into one group.

Join the islands, one bridge at a time

A bridges puzzle, also called Hashi, scatters numbered islands across a grid. You link them with straight bridges so each island has exactly as many as its number says, and the whole map ends up connected. It looks simple and rewards patient counting.

Every press of New puzzles gives a fresh set, and each one has a single answer. Start a child on the small 7 by 7 grid, where the numbers are mostly 1 and 2, or print a booklet of 13 by 13 Hard puzzles for a long afternoon. Six to a page works well for the smaller grids.

Everything happens in your browser and nothing is uploaded. Puzzles and colouring pair nicely as screen-free breaks, and our free colouring pages make a good treat once the last bridge is drawn.

Questions, answered

How do you solve a bridges puzzle?
Each circle holds a number, and that is how many bridge lines must touch it. Draw straight lines across or down between circles, one or two per pair, so every number is met and no line crosses another. When you finish, all the circles must be joined into one group.
Is this the same as Hashi or Hashiwokakero?
Yes. Bridges is the plain-English name for the puzzle the Japanese call Hashiwokakero, and many puzzle books shorten it to Hashi.
Does every puzzle have only one answer?
Yes. Each puzzle is checked as it is made, so there is exactly one way to place the bridges. Nothing is left to guesswork about which answer is the right one.
What is the difference between Easy and Hard?
On Easy you can always find the next bridge by counting alone, for example a 2 in a corner with two neighbours needs a line to each. On Hard you will sometimes need to try a bridge, follow what it forces, and back out if it clashes.
Is there a bridges puzzle for kids?
Yes. The 7 by 7 grid has about a dozen circles, mostly 1s and 2s, so children can get started with simple counting. Move up to 9 by 9 when they are ready for bigger numbers.
Can I print a whole booklet, and does it fit Letter and A4?
Yes. Choose up to 10 pages with 1, 2, 4 or 6 puzzles on each, then pick US Letter or A4. The answers come on pages at the end, six to a page.
