Marble Sort Level 304 Guide: The Iced Box and Gift Box Trap

This board is a masterclass in visual deception. You drop in, look at your targets, and immediately want to start matching left to right. Don't do it. Marble Sort Level 304 will punish you instantly if you blindly chase the first color you see.

The dominant colors you have to juggle early are Brown, Purple, and Pink, but the real star of this nightmare is the massive wall of obstacles sitting right in the center. The Top Tray is heavily layered. You have a bottom row of standard colored marbles, but right above that sits a solid row of gray question marks. You are dealing with a brutal chain of Hidden Boxes. Above that? A cluster of frozen Iced Boxes protecting the exact colors you need for the midgame. Capping it all off at the very top is a blue and red Gift Box demanding four adjacent clears before it spills its guts.

Your bottom Boxes are demanding Yellow, Purple, Brown, and Pink right out of the gate. This looks standard until you check the board and realize the trap. The Conveyor Belt has very limited space, and the game is practically begging you to make a fatal mistake on move one.

The Frozen Blockade in Marble Sort Level 304

Let's break down exactly how this board is rigged against you.

Look at the very bottom edge of the Top Tray. You have five accessible choices: Brown on the far left, Purple, White in the middle, Pink, and another Brown on the far right. This is your only safe staging area. Directly above them is an unbroken horizontal line of Hidden Boxes. You have no idea what colors are trapped inside those gray squares.

Above the mystery row sits the core problem of Marble Sort Level 304. Five Iced Boxes are locked up tight. You can see a Blue, Red, another Blue, Yellow, and Green marble locked inside the ice. You cannot drop these until you clear the adjacent standard boxes to thaw them out.

Flanking this entire icy mess are two Tunnels on the far left and right walls. Each one has a "3" stamped on it, meaning they are holding three hidden boxes in reserve. They will not drop until the space in front of them clears out. Finally, sitting dead center at the top is the Gift Box with a "4" on it.

Now look at your active lower Boxes. From left to right, you need to fill Yellow, Purple, Brown, and Pink.

Notice the massive trap here. Your very first lower Box needs Yellow. Now look back at the Top Tray. There is absolutely zero Yellow available on the bottom row. The only visible Yellow is locked inside an Iced Box deep in the middle of the board. Yellow is pure bait. If you start dropping random colors onto the Conveyor Belt hoping a Yellow magically pops out of a Hidden Box, you will clog your slots and lose the level before you even thaw the ice.

Marble Sort Level 304 Step-by-Step Walkthrough

You have to play this board strictly back-to-front. Ignore the leftmost bottom target entirely at the start. You must dig through the accessible colors to reveal the mystery row without overflowing your belt.

Beating the Opening Bait in Marble Sort Level 304

The first phase is all about precision clears to break the hidden wall.

1. Release the Purple. Tap the Purple box from the bottom row of the Top Tray. This perfectly matches the second lower Box and safely clears it off the board.
2. Clear the Pink. Tap the Pink box sitting on the bottom right of the tray. This drops perfectly into the far-right lower Box.
3. Drop the Brown. You have a Brown target active in the third column. You also have two Brown boxes on the outer edges of the Top Tray. Tap either one to clear that lower Box.
4. Hold the White. Do not touch that White box sitting in the bottom middle of the tray yet. There is no active White target on the bottom. Dropping it now just wastes a crucial slot on your Conveyor Belt.
5. Analyze the Hidden Reveal. Clearing the Purple, Pink, and Brown just exposed several of the ? Hidden Boxes. You must instantly check what colors just flipped. Only drop them if they match the newly revealed lower Boxes (which should now include Blue and more Brown based on the second layer).

Now you need to push up into the center to get that desperately needed Yellow.

6. Prioritize adjacent clears. Your main goal is to thaw the Iced Boxes. Drop any revealed colors that sit directly next to the frozen Blue, Red, and Yellow boxes. Every time you clear a box touching the ice, the ice breaks.
7. Feed the Yellow. Once you break the ice off that center-right Yellow box, drop it immediately. This finally clears out the stalled Yellow Box sitting in your first column on the bottom, unjamming the entire left side of your board.
8. Attack the Gift Box. Push straight up the middle. You need four clears directly adjacent to the top Gift Box to open it. Focus on dropping the remaining thawed Iced Boxes (the Blue and Red ones) to tick down that "4" counter.

Surviving the Tunnels to Clear Marble Sort Level 304

Once the middle opens up, the edges of the board become dangerous.

9. Watch the Conveyor Belt. The moment the Gift Box bursts, it spills multiple new colors onto the board. Pause. Look at your lower targets. Do not rapid-fire taps here. Match exactly what you need to clear the current bottom layer.
10. Trigger the Tunnels. As you clear the left and right sides of the Top Tray, the blue Tunnels will finally spit out their stored boxes. They dump three at a time. Make sure you have at least three open slots on your Conveyor Belt before you make the final clear in front of a tunnel.
11. Clean up the late colors. The lower Boxes will eventually cycle into White and Green targets. Drop the White box you saved from the very beginning, scoop up the Green marbles that drop from the Tunnels, and clear the final targets to win.
