Marble Sort Level 784 — Walkthrough and Solution

Marble Sort Level 784 is a board split into two very different halves. The left side holds quiet, single-marble dispensers and a locked Panel, while the right side hides three Tunnels that will flood your belt with a rainbow of colors the moment you touch them. The winning move is to ignore the right side completely at the start and focus all your taps on the left, clearing exactly two Boxes to pop open the Panel. Once that Panel opens, you gain access to nine Mystery Boxes that become your main arsenal for the rest of the level.

On the left side of the Top Tray, you'll find a small stash of loose Green, Red, and Blue marbles, plus three fidget-style dispensers that hold Dark Blue, Light Blue, and Orange. Above them sits a massive Panel locked with a '2' on it, meaning you must clear two entire bottom Boxes before it will unlock. In the middle of the Top Tray, a column of Iced Boxes in Purple, Pink, and Green sits frozen and unusable. On the far right, three Tunnels wait to spew a high-volume, multi-colored stream of marbles. The bottom Boxes are stacked in rows, starting with Red in the first column, Dark Blue in the second, Orange in the third, and Light Blue in the fourth. Your only initial resources are the three fidget dispensers and the few loose marbles on the left, so every tap must be deliberate.

Marble Sort Level 784 Walkthrough

The first row of Boxes demands Red, Dark Blue, Orange, and Light Blue from left to right. The left-side dispensers give you Dark Blue, Light Blue, and Orange, but no Red, so you cannot clear that first Box yet. The only viable first target is the Orange Box in the third column, because you have an Orange dispenser right there. The Dark Blue Box in the second column is your second target, also reachable with its dispenser. Clearing those two Boxes will unlock the Panel, which is your only path forward.

The real trap is the Tunnels on the right. They look like a quick way to get more marbles, but touching them early will dump colors like Purple, Green, Blue, and White onto your belt before you have any Boxes to sort them into. That will jam your Conveyor Belt within seconds. The level is designed to punish you for being impatient, so the entire opening phase is about resisting that temptation and using only the quiet dispensers on the left.

How to Beat Marble Sort Level 784 — Step-by-Step

Phase one: Unlock the Panel

1. Tap the Orange fidget dispenser on the left side of the Top Tray. This sends Orange marbles down to the third column Box, which is Orange. Keep tapping until that Box is completely cleared.
2. After the Orange Box is gone, tap the Dark Blue fidget dispenser. This drops Dark Blue marbles onto the second column Box, which is Dark Blue. Tap it until that Box is also cleared.
3. As soon as the second Box clears, the Panel's '2' countdown will hit zero, and the Panel will slide open to reveal nine Mystery Boxes. Do not touch the Tunnels yet.

Phase two: Manage the mid-game flood

1. Examine the nine Mystery Boxes that just appeared. They will show a variety of colors, including Green, Blue, and others. Start tapping the Mystery Boxes to release their marbles, but do so only when you have a matching Box on the bottom row to receive them.
2. Look at the next row of Boxes below the ones you cleared. It likely contains Green and Blue Boxes. Use the Mystery Boxes to clear those, working from left to right to keep the path open.
3. After you clear one or two more Boxes, the Iced Boxes in the middle column will thaw. They contain Purple, Pink, and Green. Tap them to release those specific colors, which will help you match the output from the Tunnels later.
4. Now you can activate the Tunnels on the right, but do it carefully. They release a mix of Purple, Green, Blue, and White. Keep an eye on your Conveyor Belt and prioritize clearing any Box that matches the color that's backing up.

Phase three: Survive the conveyor jam

1. As you clear the deeper layers, the Tunnels will become more relentless. Watch for colors that are piling up on the belt, especially Green or Blue, and find a matching Box to clear immediately.
2. If the belt gets critically full and you're about to lose, don't hesitate to use a Booster like the Magnet to clear a few marbles. This level is one of the few where a Booster can genuinely save a run.
3. Continue clearing Boxes systematically, working down through the stacks. The bottom rows contain Yellows, Reds, and more Greens, but by then the pattern is simpler. Keep the belt moving, and you'll finish Marble Sort Level 784 without issue.

Tips & tricks

• Resist touching the Tunnels until the Panel is open and you have Mystery Boxes to use. Early activation is a sure way to jam your belt.
• When the Tunnels start spewing, always check which color is piling up the fastest and clear that Box first, even if it's not the leftmost one.
• If you have a Booster, save it for the mid-game flood when the belt gets dangerously full. Using it too early wastes its power.

Common mistakes

• Activating the Tunnels before you've cleared the two required Boxes. This floods the belt with colors you can't sort, leading to an instant loss.
• Clearing Boxes from left to right without paying attention to the belt. You must react to the colors that are actually coming, not just follow a fixed order.
• Ignoring the Iced Boxes when they thaw. They contain colors you need to match the Tunnels, so use them as soon as they're available.
