Marble Sort Level 673 Guide: The Iced Cross and Hidden Box Trap

This board is an absolute trap right out of the gate. You load in and immediately see a massive central cluster holding five Iced Boxes filled with pink marbles, shaped exactly like a cross. Surrounding that frozen core is a thick shell of gray Hidden Boxes. You cannot see what colors you actually need for the midgame. To make matters worse, the outer edges tease you with exposed Dark Red, Cyan, and Orange marbles.

Your starting bottom Boxes are asking for Blue, Green, and Orange. Your Conveyor Belt has limited space. One wrong tap on a color you cannot immediately clear will clog your tray and kill the run before you even crack the first layer of ice. The entire strategy here relies on ignoring the top half of the board and surgically dismantling the bottom edge first.

The Ring of Secrets in Marble Sort Level 673

The layout of this board dictates your exact play order. You are working with a massive diamond-shaped structure in the Top Tray. The dead center is locked down by those five pink Iced Boxes. Wrapping around them is a protective ring of Hidden Boxes.

Look at the exposed tips of this formation. The top right corner holds Dark Red marbles. The very top peak has Cyan. The far left wing holds Orange. Down at the very bottom stem, you have Orange, Blue, and a block of dark Green marbles.

Now look at your starting bottom Boxes. You have four columns. The active top layers are a Blue Box on the far left, two Green Boxes in the middle, and an Orange Box on the right. Deep down at the bottom of these stacks, you can spot a Mystery Box lurking under the visible colors.

The Dark Red marbles at the top right are pure bait. They look easy to grab. Do not touch them. There is zero Dark Red space available in your starting bottom Boxes. If you pull that Dark Red, it sits on your Conveyor Belt wasting precious slots while you try to dig through the Hidden Boxes. The same goes for the top Cyan cluster.

Your entire goal is to trigger a chain reaction from the bottom up. By clearing the Blue and Green marbles at the bottom stem of the Top Tray, you expose the lower edge of the gray blocks. Tapping those revealed blocks cracks the bottom of the Iced Box cross. The lower bottom Boxes completely dictate your opening rhythm.

You need to control the board from the bottom up. Keep your eyes off the top half until the midgame opens up. Manage your belt space tightly.

Unlocking the Lower Edge in Marble Sort Level 673

Your first sequence must clear the starting bottom columns without pulling any dead weight. The right side of the board is completely off-limits right now.

1. Ignore the Dark Red marbles on the top right. Leave the Cyan marbles at the top alone.
2. Tap the Blue marbles sitting at the bottom center of the Top Tray. Send them straight into the waiting Blue Box on the left.
3. Grab the dark Green block directly underneath where the Blue just was. This will instantly fill your two active Green Boxes in the middle columns.
4. Tap the Orange marbles sitting on the far left wing of the board. This fills the active Orange Box on your right column.
5. With the first wave of bottom Boxes cleared, the board cycles. You will finally expose the lower ring of the gray Hidden Boxes. Tap the newly exposed marbles cautiously to see what colors join the board.

Shattering the Frozen Core in Marble Sort Level 673

Clearing that bottom stem changes everything. Your lower stacks will bring up new colors. Expect Yellow, Magenta, and Dark Red Boxes to rise into play. Now you can finally start fighting the central obstacle.

1. Check your new bottom Boxes. If a Dark Red Box has finally appeared, you can now safely pull those bait Dark Red marbles from the top right corner.
2. Focus on the gray Hidden Boxes adjacent to the central cross. Clearing any block next to the center will crack the ice on the neighboring Iced Box.
3. Do not pull the pink marbles from a shattered Iced Box immediately. Wait until a matching Magenta/Pink bottom Box is fully sitting at the top of a column.
4. Peel away the left side of the hidden ring. You will uncover Yellow marbles here. Drop them into the Yellow Box that just cycled up on your left side.
5. Watch your Conveyor Belt pressure. The Hidden Boxes will sometimes reveal a color you do not need yet. If you reveal a color and have no matching bottom Box, leave it exactly where it is. Work on a different side of the ice cross.

Handling the Late Board Pressure in Marble Sort Level 673

The final phase gets messy because you have shattered the ice, but you still have to deal with the bottom columns.

1. Keep pushing down the remaining columns to unmask the Mystery Box waiting at the bottom.
2. Maintain at least two empty slots on your Conveyor Belt. When the Mystery Box finally reveals its color, you might need to shuffle some remaining top tray marbles to reach the match.
3. Clear the top Cyan cluster only after the board has opened up enough to spawn a Cyan box.
4. Mop up the last exposed pink marbles from the center cross to finish the clear. Stay patient, never pull blind, and you will easily beat the jam.
