Red → Purple. The lock won't open without its key.

Marble Sort Level 161 presents a 5x4 board with three horizontal Lock and Key barriers stacked in the middle, blocking the central columns. The key to beating it is to focus on the outer columns, clear the Red and Green Boxes first, then methodically release each lock by matching its key color when the corresponding Box is available.

The Top Tray is filled with Purple, Pink, Red, White, and Blue marbles. The outer left column holds White on top, Purple below, then Light Pink, and a Blue dimpled block at the bottom. The outer right column has White, Blue, Green, and a Red dimpled block at the bottom. The three middle columns are trapped by locks: the bottom key (left side) rests on a Yellow block and locks the right; the middle key (right side) sits on an Orange block and locks the left; the top key (left) sits on a Red block and locks the right again. Under these locks are dimpled blocks: Blue, Yellow, Purple, Light Pink, and Red across the bottom row of the Top Tray.

Marble Sort Level 161 Walkthrough

The starting lower Boxes are, from left to right: a Green Box, two Red Boxes, and another Green Box. These are your immediate targets. The dimpled Blue, Yellow, and Purple blocks on the bottom left are not useful right now—they will only jam your Conveyor Belt if tapped prematurely.

The main trap is that the left side looks tempting with its Blue and Yellow blocks, but tapping them early fills the belt with colors that have no matching Boxes, causing a game over. You must ignore the left side entirely until the Red and Green Boxes are satisfied.

How to Beat Marble Sort Level 161 — Step-by-Step

Phase one: Clear the right side

  1. Tap the dimpled Red block on the bottom right of the Top Tray to send Red marbles to the waiting middle Boxes.
  2. Tap the dimpled Light Pink block next to it; park those marbles on the Conveyor Belt temporarily.
  3. Guide the Green block from the far-right outer column down to clear the first Green Box.
  4. Drop the remaining Red block from the far-right column to finish the front-line Red Boxes.
  5. With those Boxes cleared, the second layer of Boxes appears—Blue and Pink Boxes are now ready.

Phase two: Release the bottom and middle locks

  1. Wait for a Yellow Box to appear at the bottom, then tap the Yellow block under the bottom key to shatter the bottom lock, freeing the trapped Purple and Orange marbles.
  2. Shift to the far-left outer column: tap the dimpled Blue block at its bottom to fill the active Blue Boxes safely.
  3. Dig down the left column to retrieve the Light Pink and Purple blocks, sending them to their matching Boxes.
  4. Now the middle lock: it sits on the right over an Orange block. Clear the newly freed Orange marbles to drop this key.
  5. Keep an eye on your Conveyor Belt capacity—if a color is still trapped under the top lock, don't pull its matching color down yet, or you'll run out of space.

Phase three: Drop the final key

  1. Cycle the bottom Boxes until a Red Box appears, then tap the Red block under the top key to unlock the final barrier.
  2. Hold your White marbles on the top corners—White Boxes are at the back of the queue, so pulling White early is a fatal error.
  3. Flush the remaining middle blocks down the Conveyor Belt to clear them.
  4. Finally, tap the top-left and top-right White blocks to fill the last White Boxes and finish the board.

Tips & tricks

  • Always check the lower Box queue before tapping any block—only tap colors that have an active Box.
  • Use the Conveyor Belt to hold one color temporarily, but never fill it with more than two colors you can't immediately use.
  • Focus on unlocking one side at a time; the right side is the safe start, then use the freed space to tackle the left.

Common mistakes

  • Tapping the dimpled Blue or Yellow blocks early, which jams the belt with useless colors.
  • Clearing White marbles too soon—White Boxes appear last, so you'll have no place to put them.
  • Pulling a color that is trapped under a lock before unlocking it, leaving you with no space to maneuver.
