Bridges Help

Rules / Objectives Summary

• You have a collection of islands, each of which contains a number.
• This number shows you how many bridges leave that island.
• Connect every island, such that any island can be reached from any other.
• A maximum of two bridges can connect two islands together.
• Bridges can only go horizontally or vertically and may not cross each other.

See the Walkthrough or Video for extra tips and tricks.

What are the numbers for? These tell you how many bridges leave that island. When complete, all of the islands will be joined together so you can move from any one of them to any of the others. Move your mouse over the puzzle to see the answer.

Walkthrough

	Step 1 This is the start of the puzzle. Solve this puzzle for yourself at the same time.
	Step 2 The 4 clue tells us that there are 4 bridges leaving this island. But we know that the most bridges we can have to any other island is 2, so we must have 2 in each direction.
	Step 3 Similarly the 6 clue tells us that there are 6 bridges leaving this island. But again we know that the most bridges we can have to any other island is 2, so we must again have 2 in each direction.
	Step 4 For each of these islands there is only one island that the single bridge can go to.
	Step 5 Each of these islands have only one remaining bridge to find, and it's clear which islands these must join - as the other islands they can reach are either already full or we've used two bridges.
	Step 6 The remaining bridges for these islands can only go to one other island.
	Step 7 The puzzle is now complete and we can move from any island to any other.
