Watch it in action
🎲 How it works
- A Trio Box holds three different colors at once, usually 3+3+3 for 9 marbles total, feeding three different bottom boxes in one tap.
- It is about efficiency — clearing awkward bottom boxes faster when several are close to finished.
- After the tap the three colors each seek their matching bottom box; any color without a target lingers on the conveyor.
- The conveyor is your pressure meter: the more useless marbles pile up, the closer you are to a jam.
Pro tip
Use the 2-out-of-3 rule: before tapping, make sure at least 2 of the 3 colors help the board now. Read the bottom boxes first, then find the Trio Box carrying those colors. With several on board, anchor on your rarest needed color and pick the cleanest Trio Box that carries it.
