Marble Sort Level 71 punishes greed instantly. The board's defining feature is a glowing green Multiplier Gate dead center in the Top Tray, and anything dropped through it duplicates. It looks like a shortcut to clear blocks faster, but it's really the biggest trap on the board.
The Tray is a deep U-shape split into six columns. On the far left a pink block traps purple, green and hot pink above it, and the far right mirrors it with a light blue block trapping purple and dark blue. The bottom Boxes want light pink, teal, dark green and dark blue. None of the bottom blocks match those cleanly, so you dig — and any colour through the x2 gate takes up twice the belt space.
Marble Sort Level 71 Walkthrough
Chase dark blue down the left columns and the belt's left edge clogs before anything else. The move is to leave the center alone entirely until the bottom board opens up, and route your early taps through the safe right side instead.
The first Box worth chasing is that light pink one on the far right. Clear it and the whole bottom row shifts, which is what finally unlocks the midgame.
How to Beat Marble Sort Level 71 — Step-by-Step
Opening moves
- Tap the textured light blue block in the bottom-right corner (column six) and set it on the belt.
- Do the same with the textured pink block in the bottom-left (column one) — you're opening the way up.
- Leave the light green blocks beside the Multiplier Gate — and the entire centre — alone.
- Pull the dark blue from column six into your first bottom Box.
- Drag the light pink marbles out of column five to clear the far-right Box and nudge the bottom row along.
Survive the midgame jam
- Drain the purple and dark blue exposed on the left side when the purple Box appears in column three.
- When a yellow Box shows up on the far right, grab the big yellow cluster in the middle-left.
- Now use the Multiplier Gate: drop yellow through the center x2 so it doubles and fills the Box, then clears off the belt.
- Repeat for orange — wait for an orange Box, then double it through the gate so it fills and clears before it chokes the belt.
Close out the final board
- Drain whatever is parked on your belt first — light blue or pink from the start now have homes.
- Drop the last dark green blocks from the Tray.
- Never drop a colour through the gate unless its matching Box is active and waiting below.
Tips & tricks
- Treat the Multiplier Gate as a tool for the midgame only — never for the opening.
- Park the bottom-left and bottom-right textured blocks early to open the columns above them.
- Only double a colour when its Box is already front and center, so the doubled marbles clear right away.
Common mistakes
- Dropping a colour through the x2 gate in the opening. It doubles onto a belt with no home and fills it instantly.
- Forcing the left columns early to reach dark blue, jamming the left side of the belt first.
