Solve a random Easy, Medium, Hard Japanese logic puzzle chosen from today's collection. Note: If the puzzle doesn't look as it should try using 'Compatibility Mode'.
Objective / Rules - You have a collection of islands, each of which contains a number. - This number shows you how many bridges leave that island. - Your task is to 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. - For more information please read the help page.
Mouse Usage To place a bridge, click a number and drag the mouse to another number. Repeat this to place a double bridge, repeating again removes the bridge.
Checking If you click 'Check' the system will perform a very basic check. It checks for a double bridge where there should be a single bridge, and any bridge where there should be no bridge (it can't check for a single bridge where there should be a double as this isn't necessarily a mistake). If 'Show mistakes when checking' is checked they will be marked in red.
Uniqueness Each puzzle has exactly one solution, which can be found using logic alone and no guesses are ever required. If you think you've found another solution, then please double check the rules. If you still think you've found another solution, then please email us and we'll try to help.
