What is Bond Forge?

Bond Forge is a free chemistry game played on a dots-and-boxes grid. You claim a bond by answering a chemistry question pitched at your level; close a box and you score a point and go again. Play solo against the computer or head-to-head with a friend in the same match. No sign-up and no download.

The boards climb through five levels named for molecular geometry, from a small 4×4 grid up to ring-scored 8×8 matches, so the strategy gets deeper as your recall gets faster. Every right answer doubles as practice: you are drilling element names and symbols while you play, not after.
