BrainBashers : Puzzles and Brain Teasers

Free Sudoku Usage

A maximum of one Sudoku per day, of each level, may be freely used and I require recognition of copyright. A link to each Sudoku image can be found on the Sudoku Assistant page, underneath the Sudoku. The interactive version of BrainBashers Sudoku may not be used elsewhere.

General Usage

You may freely print off as many copies of any of the Sudoku as you like for your own usage, your friends, your students, etc. You must however, use the BrainBashers print option, as this will ensure my copyright is displayed. As thanks, I'd appreciate a postcard with your name, quick message and general location sent to the address below.
Printed Sudoku

For usage in a printed format the following MUST appear underneath every Sudoku:

On every Sudoku page there is a print option that has both the Sudoku and its answer in a format more suitable for printing. Once the Sudoku are printed, I ask that a copy of the first newsletter that features my Sudoku be sent to the address below.
Internet Sudoku

You may use any static Sudoku image on the Internet but the image must be hyper-linked back to www.brainbashers.com and the image must contain my copyright. As thanks, I ask that you send me a postcard with your name, quick message and general location to the address below.
