Marble Sort Level 777 is a tricky grid with a 5x6 Top Tray filled with Mystery Boxes, plus two Rocket Boosters on the left side. The solution demands that you don't tap the obvious Orange and White marbles at the start, and that you systematically clear the Blue and Purple Boxes first, saving the Brown pillar for the end.

The Top Tray holds a 5x6 arrangement where over half of the marbles are hidden behind question marks. On the upper right sit an Orange and a White marble, both traps. Below them, the bottom Boxes show a top layer of Purple, Blue, Brown, another Blue, then Yellow. The middle column is a solid stack of four Brown Boxes, a task for the finale. The left side of the Top Tray has two Rocket Boosters: one aimed at the first row, another at the fourth row.

The bottom Boxes demand, from left to right, an initial top layer of Purple, Blue, Brown, Blue, and Yellow. Underneath, the second layer includes Red, Yellow, and Purple Boxes, and the lower area holds special pop-it marbles in Red, Green, and Yellow, plus an Iced Red marble in the fourth row.

The key trap is the Orange and White marbles in the Top Tray: there are no matching Boxes for them in the upper rows, so releasing them early will block your Conveyor Belt. Also, the central Brown column is a long-term goal; tackling it too soon will jam your board.

How to Beat Marble Sort Level 777 — Step-by-Step

Phase one: Clear the Blues and Purples

  1. Leave the Orange and White marbles alone in the Top Tray.
  2. Tap the third row to reveal a Blue marble and send it to the Conveyor Belt.
  3. Carefully tap the Mystery Boxes one at a time, hunting for Blue marbles; if you reveal Pink or Dark Green, park them in the tray for later.
  4. Once you have three Blue marbles on the belt, deliver them into one of the Blue Boxes to clear it.
  5. Repeat the same process for the Purple Box, using the Purple marble visible in the fourth row, and clear the top layer of Boxes to create space.

Phase two: Use the Rockets

  1. When the Top Tray becomes cluttered with colors like Red and Yellow that you don't need yet, activate the top Rocket Booster.
  2. This clears the entire first row of the Top Tray, freeing space and revealing five new marbles from below.
  3. Now focus on the second layer of Boxes: Red, Yellow, and Purple. Hunt for marbles of these colors among the revealed ones.
  4. Keep the second Rocket Booster in reserve for emergencies; it can clear the Iced Red marble in the fourth row and surrounding Mystery Boxes if the board jams.
  5. Continue ignoring the Brown column until the end.

Phase three: Finish the Final Stacks

  1. As you reach the bottom of the Top Tray, use the pop-it marbles (Red, Green, Yellow) to clear the remaining Boxes of those colors.
  2. With most colors gone, finally focus on the Brown column. Collect Brown marbles from the tray or Mystery Boxes and clear all four Brown Boxes.
  3. If you still have the second Rocket Booster, use it to clear any inconvenient marbles.
  4. Clear the last few Boxes to conquer Marble Sort Level 777.

Tips & tricks

  • Always tap Mystery Boxes one at a time to control what colors you reveal.
  • Use the Conveyor Belt as a temporary holding area for marbles you need to collect.

Common mistakes

  • Releasing Orange or White marbles too early, which clogs the Conveyor Belt.
  • Focusing on the Brown column before clearing other colors, leading to a jam.
  • Wasting Rocket Boosters on trivial moves, leaving you stuck later.
