Read the mechanism before acting
Before tapping a source, inspect the reaction context and identify the electron pair or bond that moves. Then locate the sink that receives it. Treat the curved arrow as a representation of electron flow, not a line to draw anywhere that seems plausible. The listed mechanisms differ, so use the in-game prompt and your chemistry knowledge rather than applying one sequence mechanically.
Use the clock deliberately
The clock adds pressure, but rushing through source and sink choices can make a plausible-looking arrow incorrect. Read the current step, act, and then use the feedback to understand what the mechanism requires. If you know one reaction more confidently than another, let that inform your speed; do not let the countdown replace checking the reaction logic.
Pay attention to story choices
The campaign’s choices can change its ending. They are part of the narrative, separate from the curved-arrow mechanism actions. Read the choice before selecting it if you want to follow a particular story direction. Lab Notes is described as advanced organic chemistry play, so it may suit players already familiar with mechanisms; its game card gives the actual campaign entry.
Questions about Lab Notes game tips
Which mechanisms appear in Lab Notes?
The campaign includes SN2, SN1, E2, Grignard and Fischer esterification mechanisms.
Do choices change the story?
Yes. Choices can change the campaign’s ending. Mechanism steps use taps on electron sources and sinks to push curved arrows.
