Dear visitor I would like to have a moment of your time please. All the games and puzzle on my website are for free, but I have my costs to keep this website up and running. Please consider to donate a small amount to the creator of www.edu-games.org, if you download multiple worksheets. You can find the donate button in the bottom right corner of the website. Thank you in advance. Printable Brain teaser worksheets Welcome to the edu-games brain teasers. I just start to work on the brain teaser section. In the near furture you will find here more teasers.
