Archimedes-lab.org is a free and collaborative edutainment website developed and maintained by Gianni A. Sarcone and Marie-Jo Waeber, two authors and writers with more than twenty years of experience in the fields of visual thinking and education. The main goal of the site is to popularize math through puzzles and games.

Archimedes-lab.org is divided into three main categories: puzzles & tests, illusions & paradoxes, oddities & curiosities. Among the proposed educational things, visitors will find number games, riddles, puzzles with downloadable pieces, perception puzzles and interactive optical illusions. A principal objective throughout the site is the enhancement of critical thinking skills. Here’s a quote from Scientific American (May 27, 2003): "This virtual lab borrows the empirical spirit and creative curiosity that Archimedes brought to his work and invites visitors to explore with the same expectations for mind-blowing discovery."

Archimedes-lab.org has won several awards from scientific and educational publications, including a Scientific American Web Award in 2003, the NCTM (National Council of Teachers of Mathematics) Webby, and a mention in Merlot, the Multimedia Educational Resource for Learning and Online teaching.
