Yellow → Pink. The lock won't open without its key.

Marble Sort Level 225 is a two-part board split by a massive Lock and Key mechanic. You must sprint to the top right corner for the Key before you even glance at the left side. The moment you break that chain, the entire board opens up, but until then, any wrong tap jams your Conveyor Belt.

The Top Tray is divided into a tall right-side 3x5 grid and a lonely left column. A huge vertical chain locks the left column of that right grid, trapping Pink, Brown, Purple, Blue, Orange, and another Pink inside. On the white box at the top right sits the Key. The isolated left column holds a dark blue Tunnel marked "3" and three pairs of Connected Boxes below it: Orange-Brown, Light Blue-Purple, and Green-Pink. Your bottom Boxes start with Yellow on the far left and far right, with Dark Blue and Brown hiding in the middle columns.

Your bottom row demands Yellow first, then Pink, Dark Blue, and Brown. The far right column shows three Yellow boxes stacked, and the far left has one Yellow on top. Those are your only safe taps until the Key is secured.

The trap is that the right side looks open, but every box you pull from the locked column drags extra colors onto your belt. You must tunnel straight up the right and middle columns, ignoring the left side entirely, to reach the Key before the belt chokes.

How to Beat Marble Sort Level 225 — Step-by-Step

Phase one: Rush for the Key

  1. Clear the four Yellow boxes from the bottom: tap the three in the far right column and the one on the far left.
  2. Match the exposed Pink and Brown in the bottom row of the right-side grid to empty those bottom Boxes.
  3. Dig upward through the right and middle columns, only tapping boxes that directly match an available bottom Box.
  4. Keep your belt under four marbles; if you must pull a Blue to reach a Yellow, plan to match that Blue immediately.
  5. When you reach the top right white box, tap it. The Key drops, the chain shatters, and the locked column becomes playable.

Phase two: Dismantle the connected pairs

  1. Before touching the left side, clear the newly exposed Pink at the bottom of the freed column and any other easy matches on the right to empty your belt.
  2. Look at the left column: the first pair is Orange and Brown, tied together. Do not tap either unless you have both an Orange and a Brown bottom Box ready.
  3. When the lower boxes ask for those colors, tap the pair once to drop both. Let the belt settle.
  4. Wait for the next demand: Light Blue and Purple. Then trigger that pair.
  5. Finally, the Green-Pink pair. Release it only when both colors are needed, and then clean up any remaining right-side boxes.

Phase three: Survive the Tunnel drop

  1. Once the last Connected Pair is gone, the Tunnel at the top left activates.
  2. It spits out three hidden boxes one after another, with unknown colors.
  3. Make sure your belt is nearly empty before the drop; any leftover marbles will cause a game over.
  4. Match each new box directly into an available bottom Box as it appears.
  5. Clear the last isolated boxes from the right grid and finish the level calmly.

Tips & tricks

  • Always count your belt space before pulling any pair; six marbles at once can flood you.
  • When the Tunnel activates, pause and look at your bottom row before tapping anything.
  • Use the right side as a temporary buffer; park unwanted colors there if you have space.

Common mistakes

  • Tapping a Connected Pair when only one of its colors is needed, leaving the other to jam your belt.
  • Triggering the Tunnel with a half-full belt, causing an instant game over.
  • Digging evenly across the right grid instead of going straight up, delaying the Key.
