- 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 use the BrainBashers print option, as this will ensure the copyright is displayed.
- Sudoku In Print
A maximum of two Sudoku per day may be freely printed in any free or commercial publication (i.e. no individual print run may use more than two BrainBashers Sudoku). We require recognition of copyright and the following MUST appear underneath every Sudoku (and solution):

On every Sudoku page there is a print option that has both the Sudoku and its answer in a format more suitable for printing.
- Internet Sudoku
You may use up to 20 static Sudoku images but the images must be hyper-linked back to www.brainbashers.com and you must clearly display our copyright.
