# Beat Bars

Fractions · 30 levels

Fill each neon bar with notes that make one whole.

## How to play

- Select a note gem at the bottom, then tap a bar to add it. Selection stays active while copies remain: tap a bar again to add another. Selecting the same gem again keeps it selected. Tap a gem in a bar to take it back.
- A gem's length is a fraction of a whole note: ½, ¼, ⅛, dotted ⅜, triplet ⅙ … Dim gems are locked in.
- Fill every bar to exactly its time signature (4/4 = 1 whole, 3/4 = ¾). Spare gems may stay. Then the track plays!

Press ▶ any time to hear your track; a bar that isn't full flashes red. Triplet ⅙ gems only fit three at a time (⅙ + ⅙ + ⅙ = ½).
