Marble Sort Level 274 is a symmetrical board that looks like a colorful playground but is actually a trap. The key to beating it is to ignore the tempting Dark Blue and Dark Green marbles at the start and focus only on the Orange and White pairs on the far edges. These are the only colors that have matching empty Boxes waiting at the bottom, so routing them clears space and triggers the Mystery Boxes to reveal the missing Magenta and Light Green you desperately need.
The Top Tray is dominated by four large wooden crates with X marks, which are protected by a U-shaped wall of gray Mystery Box units. The front row, from left to right, has a White block, Dark Blue, another White, two Dark Green blocks in the center, Light Blue (Cyan), and an Orange block on the far right. Your four bottom Boxes require, from left to right, Orange, Magenta/Pink, White, and Light Green. The problem is that Magenta and Light Green are nowhere visible on the front line, so you must unlock them by clearing the Orange and White targets. Underneath the starting Boxes, you'll find Dark Green, Brown, Yellow, and Cyan waiting, and the top blue Tunnels labeled 3 will later dispense more marbles once the crates are broken.
Marble Sort Level 274 Walkthrough
Your bottom Boxes, left to right, demand Orange, Magenta/Pink, White, and Light Green as their top layers. Clearing those first four top layers will reveal the next set: Dark Green, Cyan, Yellow, Brown, and another White. The front row is a decoy—Dark Blue and Dark Green are exposed but have no matching Boxes yet, so tapping them early jams your Conveyor Belt.
The real imbalance is that Magenta and Light Green are buried under the Mystery Boxes. You must clear the Orange and White pairs to force those Mystery Boxes to flip, revealing the missing colors. The Dark Green and Cyan marbles in the center can only be cleared after their bottom Boxes become active, which happens once you've filled the first four Boxes. The entire early game is about unlocking the Mystery Box layer without choking your workspace.
How to Beat Marble Sort Level 274 — Step-by-Step
Phase one: Clear the Front Line
- Tap the Orange marbles on the far right of the Top Tray and deliver them to the leftmost bottom Box, emptying it.
- Slide the White marbles from the far left of the Top Tray into the third bottom Box, clearing it.
- Watch the Mystery Boxes flip—when Magenta/Pink appears, route it to the second Box.
- When Light Green shows up, guide it to the fourth Box, completing the first row.
- Now that the Dark Green and Cyan bottom Boxes are active, drop the Dark Green marbles from the center into the left Box and the Cyan marbles into the third Box.
Phase two: Shatter the Crates
- Pick the right side of the U-shaped Mystery Box wall and clear every flipped Mystery Box you can match there.
- After three adjacent boxes are dropped, the lower right crate shatters, releasing Pink, Brown, and Yellow marbles—only drop them if their Boxes are open.
- Switch to the left side and clear the Mystery Boxes there to break the lower left crate.
- Once the space under the blue Tunnels is clear, they activate and each dispenses three marbles in sequence—treat these as urgent priorities because they block the upper crates.
Phase three: Finish the Tunnels and Final Crates
- Monitor the numbers above the Tunnels; when a Tunnel hits zero, that lane is done.
- After all Tunnels are exhausted, the final two top crates break, flooding the board with Pink and Blue marbles.
- Keep your Conveyor Belt nearly empty before that flood—if more than three junk marbles sit there, you'll fail.
- Clear only the exact colors matching the final row of bottom Boxes, which cycle through Blue, Yellow, and Brown, to complete the level.
Tips & tricks
- Always prioritize clearing the Orange and White pairs first—they unlock the Mystery Boxes that hold Magenta and Light Green.
- Never tap Dark Blue or Dark Green until their bottom Boxes are active; otherwise, they'll clog your Conveyor Belt.
- When a crate shatters, quickly assess the new colors and drop only those that have an open Box—ignore the rest.
- Keep your Conveyor Belt as empty as possible before the final crate break; you'll need the space for the Pink and Blue flood.
- Focus on one side of the Mystery Box wall at a time to break crates efficiently, rather than spreading your effort.
Common mistakes
- Tapping Dark Blue or Dark Green early because they look like easy targets—this jams your belt instantly.
- Alternating between left and right sides of the Mystery Box wall, which delays crate breaking and causes clutter.
- Ignoring the Tunnel dispensers when they activate; if you don't clear them promptly, they block access to the upper crates.
- Letting more than three junk marbles accumulate on your Conveyor Belt before the final crate break—this guarantees a loss.
- Dropping marbles that don't match any active Box after a crate shatters, wasting space and moves.
