Welcome to the Gridlocks homepage brought to you by the RSC and Wolfson Foundation. Gridlocks are a fun way to learn the facts you need in Chemistry. Unlock the grids to gain entry to the next level and a secure knowledge of the chemistry involved. Based on the ideas behind Su Doku, Gridlocks have a twist that makes them more interesting, more fun, and more useful.

If it's your first time at a gridlock be sure to view the instructions on how they work, otherwise it's time to get started...
