Marble Sort Level 274 Walkthrough & Solution

Level 274 Board Overview: The U-Shaped Crate Blockade

Level 274 uses a dark board with a U-shaped wall of grey mystery boxes. Four wooden crates occupy the upper and middle lanes, while White, Dark Green, Dark Blue, Cyan, Orange, Yellow, and Purple groups remain visible around them. Four blue Tunnels sit along the upper edge, each starting at a 3-counter.

The front receiver row asks for Orange, Magenta-Pink, White, and Light Green. Magenta-Pink and Light Green are hidden behind the first mystery layer, so the safe opening is Orange on the right edge followed by White on the left. Dark Green and Dark Blue are bait until the row shifts.

The Trap in Marble Sort Level 274

• The exposed colors are not all safe: Dark Blue and Dark Green look easy, but the opening receivers do not ask for them.
• The mystery wall is a U, not a straight line: clear one side consistently so three neighboring clears can shatter a lower crate.
• The four tunnels have 3-counters: their batches arrive after the crates open, so preserve belt space before starting the tunnel phase.

Marble Sort Level 274 Step-by-Step Walkthrough

Opening: reveal the front receivers

1. Leave the Dark Blue and Dark Green groups alone.
2. Tap the Orange group on the far right and send it to the opening Orange receiver.
3. Tap the White group on the far left and clear the White receiver in the third column.
4. When the first mystery layer flips, feed any revealed Magenta-Pink and Light Green groups into the two remaining front receivers.
5. Once those four front boxes shift, bring the matching Dark Green and Cyan groups out of the center.

Midgame: break the two sides of the wall

The front row is now open, but the four crates still hold the upper half of the board. Pick one side of the U-shaped mystery barrier and clear it continuously. Three adjacent box clears shatter the lower-right crate; the new Pink, Brown, and Yellow groups should be matched only when their receivers are active.

6. Stay on the chosen side of the mystery wall until the lower-right crate breaks.
7. Route the Pink, Brown, and Yellow groups from that crate into their matching receivers.
8. Work through the opposite side of the U to break the lower-left crate.
9. Keep the top two crates untouched until the lower lanes and the belt have enough room for their spill.

Cleanup: survive the tunnel batches

Once the lower crates are gone, the blue Tunnels begin dispensing three sets each. Their counters show how much remains. The final two crates break after the tunnel lanes drain, revealing the last Pink and Blue groups.

10. Treat each tunnel batch as an immediate priority and match its color before the next drop.
11. Watch the counters until all four tunnels reach zero; do not park more than a few unmatched marbles on the belt.
12. Clear the final Pink, Blue, Yellow, Brown, Cyan, and Green groups in the order requested by the last receiver row. The level completes when the last crate spill lands.

Level 274 Tips Recap

• Open with Orange and White; Dark Blue and Dark Green are bait.
• Reveal Magenta-Pink and Light Green before touching the center stacks.
• Clear one side of the U-shaped wall at a time to break the lower crates.
• Save belt space for the four 3-counter Tunnels.
