Bridges puzzles look like a map, which is most of why children take to them. Circles are islands, the number inside each one says how many bridges must touch it, and you join them with straight horizontal or vertical lines until every island has the right count and the whole map is connected. The sets on this page use few islands and small boards, so a child can see the whole puzzle at once and finish one in a few minutes rather than losing heart halfway.
Small hashi boards with widely spaced islands and clue numbers printed large inside each circle, so there is plenty of room to rule bridges between them without the lines touching the numbers. Each puzzle has an answer page showing the finished network, single and double bridges included. Black and white, one puzzle per US Letter page.
Draw straight lines between circled islands, going only up, down, left or right. The number in an island is exactly how many bridge ends must meet it. You may draw at most two bridges between the same pair of islands, bridges may not cross each other or pass through an island, and when you finish, every island must be reachable from every other one.
What is the easiest first move?
Look for an island marked 1 sitting next to only one other island — its single bridge is forced. Then look for a 4 with only two neighbors: it needs two double bridges, so both are certain. Islands whose number equals twice their number of neighbors are always fully forced.
What age are these suitable for?
As an editorial suggestion, around ages 7 to 10 for this set. The counting involved never goes past eight, and the appeal is visual rather than numerical, so children who dislike number worksheets often enjoy these anyway.
Do you need a ruler?
It helps but is not necessary. Freehand lines are fine as long as it is clear which two islands each bridge joins. Some children like using a ruler because the finished puzzle looks like a proper map, which is part of the reward.
