What can I do with my Sudoku?

You have many options open to you. You may print your generated Sudoku to take with you on a train journey, for a long Friday at work or for a lazy afternoon in the park. Whenever you have some free time, you can keep your mind busy with a couple of Sudoku at hand.

If you wish to take part in a newspaper competition, you may solve a Sudoku and email it to yourself. From here, you will be able to forward it on to the competition email address. If you want to take part a postal entry, simply print off your Sudoku and send it in.

Sudoku puzzles generated here cannot be sold in any form. They may not be used on external websites or any publications. We do allow individual Sudoku to be used on other websites if they are for non-commercial purposes with a credit. If you are unsure on our Sudoku copyright, please contact us.

My Sudoku is invalid with multiple solutions.

Your Sudoku has not been generated at Sudoku Solver. All of our Sudoku, Super Sudoku and Samurai Sudoku puzzles are verified before display. In addition, the Sudoku generator program only uses varying levels of logic to create the puzzles. Guessing is not logical, guaranteeing that all the Sudoku here are unique.

If you are using the Sudoku solvers, multiple solutions simply reflect badly on the source of the Sudoku.

Why does my account not work?

Please read over your welcome email for your username and password. All accounts must be verified before you can use the Sudoku generators and solvers. Simply follow the instructions in your email to verify your account.

Another reason may be that we have spotted an irregularity with a new account and it has been removed. There are a number of reasons why we would close an account, see below for more information.

Why can't I stay logged in?

There is a cookie problem if you are continually redirected to the login page, after you have logged in. You need to enable session cookies in your browser.

How do I enable session cookies?

In Internet Explorer, go to Tools | Internet Options | Privacy | Advanced... then tick "Override automatic cookie handling" and then tick "Always allow session cookies".

Why does it say I have reached my daily limit? I have not used my account today.

The days are measured in UK time. New days will begin at around 7 pm in the US, and 11 am in Australia, depending on your time zone.

Why do you need to verify my email address?

We want to stop people registering multiple free accounts without valid details. Valid email addresses are vital for a number of reasons.

• Firstly, we can only send you a copy of your account details to you if your email address is working.
• Secondly, any generated or solved Sudoku will be emailed to your account address by default. If this address does not exist, then you lose your Sudoku.
• Finally, many members would like to receive news from Sudoku Solver delivered to their email inbox. Obviously, if the email address is bad, you will miss out here.

Why do you close some accounts?

Any accounts created with invalid details for the name or email address will be removed.

People who continually create multiple free accounts or continually enter invalid details will be banned. Anyone found breaking our copyright guidelines will be banned.

What is the newsletter?

The newsletter will simply contain Sudoku Solver website news, general Sudoku news, information on competitions and Sudoku freebies.

We will not bombard your email inbox with endless promotions as this is simply annoying to everyone. Our newsletters will never be sent more than once a month and your email will not be given to anyone else.

What new features will arrive at Sudoku Solver in the future?

We have a number of unique features that will soon be arriving on this website. A Killer Sudoku solver and generator, a competitive Sudoku community game and a general Sudoku "work area" will be introduced to allow people to solve their Sudoku online as they currently would do on paper.

How may I contribute?

At the moment we are looking for a number of user contributions that you may wish to partake in. Anyone that provides a useful contribution will be entitled to a free account upgrade.

• General site suggestions would be very welcome.
• Offers of prizes or prize suggestions for future Sudoku Solver competitions.
• Links to other genuinely interesting Sudoku websites.
