Marble Sort Level 150 Walkthrough & Solution

Level 150 Board Overview: Crates, Mystery Tiles, and a Full Belt

Level 150 is flagged Very Hard, and the board earns it before you make a single move. The top tray runs five tall columns, but the two corners are sealed: a wooden crate stamped with a 4 caps the left stack, and crates stamped 4 and 3 stack up over the right one. Between them, gray mystery tiles cover a couple of slots near the center, hiding what sits underneath.

Below the tray, eight receiver boxes wait — but on the opening board only about half of them show a color label. Orange, Cyan, Purple, and Yellow are visible; the rest are gray mystery boxes that reveal their color as you play. That asymmetry is the whole puzzle: you have far more marbles on the belt than you have confirmed destinations.

The conveyor is already loaded when the level starts, with clusters of Purple, Cyan, Orange, and Red riding the track. Midgame the queue only gets heavier, adding long runs of White, Yellow, and Green. Whoever you release, you release into a belt that never stops, so every tap has to count.

The Trap in Marble Sort Level 150

This level is designed to make you dump marbles before their boxes exist:

• Four mystery boxes hide your targets. Roughly half the receiver row starts as gray ’?’ tiles, so the colors you actually need (Blue, Pink, Red, Green appear later) are invisible at the start.
• The crates wall off the best colors. The Blue stack on the left and the Purple stack on the right are buried under numbered crates. They read as progress meters — every Blue and Purple you collect ticks them down — but the marbles themselves stay locked until the count finishes.
• The belt starts full. Purple, Cyan, Orange, and Red clusters are already queued on opening. If you release a color whose box is still a ’?’, it parks on the belt and blocks everything behind it.
• The center stacks are mixed. The middle columns layer Pink over Red over Green and Green over Yellow over White, so clearing one color usually exposes another color that has no box yet.

Marble Sort Level 150 Step-by-Step Walkthrough

The whole run is about matching your taps to whatever boxes are currently revealed. Follow the phases in order.

Opening: play only the revealed boxes

1. Survey the board before tapping: crates seal the left and right corners, mystery tiles sit near the center, and only a handful of boxes are labeled. The exposed column tops are your only safe marbles.
2. Check the receiver row first and note which colors have open boxes — on this board Orange, Cyan, Purple, and Yellow are labeled from the start.
3. Tap the topmost marble of any stack that matches an open box and let it ride the belt down. Orange and Cyan are the safest early colors.
4. Do not release Red, White, or Green yet. The queue already carries Red and Purple clusters, and none of those boxes are showing.
5. Keep the belt moving, but never empty a stack whose color has no box. If the front of the queue stalls, wait for the next mystery box to flip instead of dumping an unboxed color.

Midgame: the mystery boxes flip open

Once a few labeled colors clear, the ’?’ boxes start revealing — Blue, Pink, Purple, and Red boxes appear in the receiver rows, and the center columns finally become playable.

6. Clear the Pink on top of the center-left stack into the Pink box.
7. Immediately follow with the run of Reds sitting beneath it — the Red boxes are live now, and the stack empties fast.
8. Move right: the tall Green-over-Yellow-over-White stack feeds Yellow into its box as it cycles to the front.
9. The conveyor is now heavy with White, Cyan, Yellow, and Purple. Feed Cyan and Yellow whenever their boxes show; let Purple wait on the belt if no Purple box is up.
10. Watch the numbered crates on every Blue and Purple tap — the counts over the corner stacks tick down, so keep collecting those colors whenever a matching box is open.

Cleanup: pop the crates and drain the queue

11. When the crate over the left stack finally pops, release the Blues beneath it into the Blue boxes in one clean run.
12. When the right crate pops, dump the Purples the same way — they have been stacking on the belt all game.
13. From here the tray holds mostly leftover Green and Red plus the tail of the queue. Play to the front row of boxes only; do not start a color whose box is not showing.
14. Feed the last queue marbles (Yellow, Red, Blue, Green, Pink) as their boxes come around, and the remaining crates clear on their own.

Level 150 Tips Recap

• Only release marbles whose box is currently labeled — the ’?’ boxes are the level’s whole trap.
• Collect Blues and Purples whenever you can to tick down the corner crates; their stacks are the prize at the end.
• The conveyor arrives full, so a single unboxed tap can jam the entire run. When in doubt, pass.
• In the endgame, clear the leftover Green and Red and play strictly to the active boxes to finish the Very Hard board.
