Mastering organic chemistry requires hands-on practice with chair conformations. This puzzle game offers fun and effective exercises to develop spatial reasoning skills.

Master organic chemistry with the only interactive puzzle game designed for understanding chair conformations. Awarded “top chemistry app” by the Royal Society of Chemistry and 2016 finalist for the SXSW LaunchEDU award.

Success in organic chemistry courses and on exams such as the MCAT, GRE or DAT requires learning to think visually. Hands-on practice is critical to success.

Memorizing terms and formulas might get you through general chemistry, but may lead to failure in organic chemistry.

Chair conformations, called ring flips, offer great exercises in spatial reasoning, which is key for mastering organic chemistry. Yet hand drawing these cyclohexane chair forms can be tricky.

We created this game to prove organic chemistry can be visual, tactile and, yes, entertaining.

This visual pattern puzzle game provides a fun and fast method for mastering chair (or cyclohexane) ring flips.

Chairs! takes the mystery out of ring flips by offering instant feedback. During game play, as levels increase, so too does the complexity of these organic chemistry puzzles against the clock. There's no need to understand organic chemistry to play.

With over 13 challenging levels, we will help you master this tough concept with ease.

Recommended by professors at the University of Minnesota, University of Michigan, University of Edinburgh, and others.

Take off the timer or put an option where we can turn it off

I want to learn, not panic about the time running out. It’s annoying.

Remove timer

Would be perfect if timer was optional, very annoying to learn when only 1-3 seconds per puzzle around ~35

Not worth the $

I could learn better with a modeling kit. There’s no instruction to what you’re even looking for or what to do. It’s a good idea in theory, just not well implemented
