Backside Attack is an educational app targeting students learning organic chemistry for the first time. The game focuses on the SN2 reaction, which is often one of the first reactions students learn when studying organic chemistry. The SN2 reaction is great for educational purposes, as it provides a forum for students to learn about many common variables associated with chemical reactions, such as leaving group ability, nucleophilicity, steric factors, and solvent effects. The Backside Attack project is led by Dr. Neil Garg, an organic chemistry Professor at UCLA. He and six UCLA students (now alumni) devoted countless hours to creating the game flow and all content. The heroic students are: Tara Kappel, Preeya Mehta, William Parsons Stefan Prisacaru, Ernst Schmid, and Justin Soffer. Backside Attack is powered by Element26, Inc., thanks to Dr. Daniel D. Caspi.

Backside Attack holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Backside Attack has 74 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 95% of Backside Attack's written reviews are positive against 100% of Colby Safe's, so the app with the better star average is not the one people write more warmly about.
Backside Attack ships an update every 8 months, Colby Safe every 28 months. The most recent releases landed on July 4, 2026 and September 17, 2026 respectively.
