Marble Sort Level 709 — Walkthrough and Solution

Marble Sort Level 709 is a puzzle where the board splits into two very different halves. The key to winning is to clear the initial Dark Red and Dark Blue Boxes first, then manage the bubble bursts carefully, and finally dismantle the right-side stacks to open the Tunnels. Do not touch the right side until the left side is mostly cleared.

The left side of the Top Tray is dominated by a large grey Surprise Bag with question marks. Inside that bag, near the center, a dashed square holds four large bubbles: Green, Dark Blue, Orange, and Black. The right side of the Top Tray has two vertical stacks. The far right stack, from top to bottom, contains Green, Cyan, Pink, Purple, and Light Green. The stack next to it has Dark Red, Green, Yellow, Blue, and Black from top to bottom. Above these stacks, two Tunnels are marked with the number 3, but they stay blocked until the stacks are gone. At the very bottom of the Top Tray, there is a single free Dark Red marble. The starting bottom Boxes, from left to right, are three Dark Red Boxes and one Dark Blue Box, all demanding to be filled immediately.

Marble Sort Level 709 Walkthrough

Your first task is to fill the three Dark Red Boxes and the one Dark Blue Box. The only visible Dark Red marble is the one at the bottom right of the Top Tray. The other needed colors are hidden inside the Surprise Bag, so you must reveal them one by one.

The main trap is the Surprise Bag. You have no idea what colors are inside, and pulling out the wrong ones can fill your Conveyor Belt with useless marbles. The right side stacks are a decoy; touching them early will cause a jam because their colors cannot be used yet.

How to Beat Marble Sort Level 709 — Step-by-Step

Phase one: Clear the Front Boxes

1. Tap the single Dark Red marble at the bottom right of the Top Tray and route it to the first Dark Red Box.
2. Now, gently tap the edges of the Surprise Bag to reveal the hidden marbles. Look for Dark Red and Dark Blue.
3. When you uncover a Dark Red marble, send it to the next empty Dark Red Box. Do the same for any Dark Blue marble.
4. If you reveal a marble of a color you do not need, leave it in place if possible. If you must move it to reach the one behind, let it sit on the Conveyor Belt for a moment, but do not let too many pile up.
5. As soon as you find a matching marble for a front Box, clear that Box immediately. Finish all four front Boxes before moving on.

Phase two: Pop the Bubbles

1. After the front Boxes are done, the bottom row will change, now asking for Yellow, Orange, and other colors. The central dashed square becomes accessible.
2. Wait until the Orange Box is active on the bottom row, then tap the Orange bubble. It will burst and release a large group of Orange marbles down the chute.
3. Similarly, wait for the Black Box to appear, then pop the Black bubble. Do not pop any bubble unless its matching Box is ready, or the flood will overwhelm your Conveyor Belt.
4. Continue to remove the Surprise Bag fabric piece by piece as the bottom Boxes demand new colors. Always check which Box is open before revealing a new section.

Phase three: Dismantle the Right Stacks and Tunnels

1. Once the left side is mostly empty, focus on the right vertical stacks. Start with the bottom marbles of each stack.
2. Drop the Green marble from the second stack into its matching Box, then the Cyan from the far right stack, and so on. Work upward, always matching the current color to an open Box.
3. After you clear an entire stack, its Tunnel activates. The Tunnel will release three new marbles, one at a time. Handle each drop immediately, matching it to the correct Box.
4. Finish all remaining Boxes using the Tunnel marbles and the last few from the Surprise Bag to secure the win.

Tips & tricks

• Keep your Conveyor Belt as empty as possible. If you have to move a useless marble, park it at the far end of the belt and clear it soon.
• When popping bubbles, always double-check that the correct Box is open. A single mistake can flood the board.
• Use the Surprise Bag reveal order to your advantage: if you see a color you need later, try to keep it accessible for when its Box appears.

Common mistakes

• Touching the right side stacks too early. This will mix colors you cannot use and jam your Conveyor Belt.
• Popping a bubble without the matching Box ready, causing a massive overflow that is hard to recover from.
• Releasing too many useless marbles from the Surprise Bag at once, filling your Conveyor Belt and leaving no room for the needed colors.
