Marble Sort Level 43 — Walkthrough and Solution

Level 43 is the connected box trap. A Brown-and-Red Connected pair seals the middle with no Box waiting for either colour — clear the White and Yellow flanks first, then snap that centre link only the instant a Red Box slides forward.

⚡ Quick clear

Yellow → Pink. Only drop a colour when its box is ready.

Marble Sort Level 43 dares you to pop the two fat blocks in the centre and lose on the spot. The colours that matter early are White, Yellow, and Light Pink, and the whole solve is clearing both outer flanks before you ever touch the Brown and Red pair squatting mid-board. Break that pair early and two colours flood the Conveyor Belt with nowhere to land.

The Top Tray rises in uneven steps, with a pair of Tunnels stamped 3 tucked into the top corners. Its base holds a White cluster on the far left, a Yellow cluster on the far right, and one Connected Box between them that welds Brown to Red. The front row of bottom Boxes wants Yellow, then Light Pink, then two Whites.

Marble Sort Level 43 Walkthrough

Those four targets are kind as long as you stay disciplined: column one asks for Yellow, column two for Light Pink, and columns three and four both want White. Behind the front line sit dark green, light pink, light blue, and purple blocks, so the second layer is where the real digging starts.

The Light Pink you need for column two is the awkward one — it sits tucked behind the left edge of the Connected Box and a dark green block. Meanwhile the Brown-and-Red centre is a trap: neither colour has a Box anywhere, so releasing it dumps junk you cannot sort.

How to Beat Marble Sort Level 43 — Step-by-Step

Clear the outer flanks first

  1. Send the White block on the far left down so it fills the two White Boxes in columns three and four.
  2. Watch the lower row shift: column three now shows a Yellow Box and column four a Light Green Box.
  3. Route the Yellow block on the far right into the Yellow Box in column one and the fresh Yellow Box in column three.
  4. Keep your hands off the Connected pair. With no Red or Brown Box live, touching the centre is a loss.

Dig the second row for Light Pink

The flanks gone, the board hands you a new front line.

  1. Read the new front row — Light Pink, Purple, and Light Green are now showing.
  2. Feed the Purple blocks that came free on the right into the Purple Boxes sliding down.
  3. Bank the dark green block on the left onto the belt to uncover the Light Pink behind it.
  4. Release that Light Pink to finish the stubborn column-two Box.
  5. Hold until a Red Box slides forward; the moment it does, tap the Brown-and-Red Connected pair — the Red clears instantly and the Brown has room to wait.

Drain the two Tunnels

  1. Hit the two Tunnels stamped 3 early — six hidden blocks live up there, so do not save them for the end.
  2. Clear the blocks directly beneath a Tunnel, then tap the Tunnel to force its first colour out.
  3. Reveal a Tunnel colour, match it to a bottom Box, then tap the Tunnel again for the next one.
  4. Pull from a single Tunnel at a time; firing both at once spits conflicting marbles and jams the belt.

Tips & tricks

  • Leave the centre untouched at the start. The Brown-and-Red pair has no Box, so it is a two-for-one flood of junk.
  • The dark green block is a one-tap hold that buys you the Light Pink — cheaper than a stuck column two all game.
  • Snap the centre only when a Red Box is front and centre, so the Brown half has room on the belt.

Common mistakes

  • Firing the Brown-and-Red pair early. Both colours lack a Box, so they pile up and leave no room for the White and Yellow clears you need.
  • Pulling both Tunnels at once. Their random colours collide on the belt before you can sort either one.
