Six things on the left, six labels on the right, and a clock that keeps moving. Pair them all to clear the bench and win back time.
The bench. Each round deals six pairs. Tap one card on the left, then the label on the right that belongs to it. Tapping in the other order works just as well.
The clock. You start with 120 seconds for five benches. A correct pair adds nothing but points. A wrong pair costs four seconds. Clearing a whole bench wins ten seconds back.
Points. A pair is worth 300. Three in a row lifts the multiplier, and it keeps climbing to three times. A miss drops it back to one.
Reading the drawings. On the shapes bench, lines are bonds and small paired dots are lone pairs. A bold wedge points toward you and a dashed line points away. Count every bond and every lone pair, then name the shape.
Keyboard. Tab moves between cards and Enter or Space picks one. Every match prints a short reason underneath the bench.
