Step-by-step solution
- 1) Flick the White tile at the bottom-center of the Top Tray so its 9 Whites fill the White receivers capping Slot 1 and Slot 2, leaving exactly 3 Whites parked on the belt.
- 2) That White clear exposes a Light Green tile behind it in the center column, while Slot 1's White Box reveal hides another Light Green receiver under it; tap that Light Green block to fill both boxes and park 3 extra Light Greens on the belt.
- 3) After the first two layers clear, Yellow Boxes appear in Slots 1, 2, and 3, so grab the far-left and far-right Yellow blocks and let all 9 flow into the three waiting receivers with zero waste.
- 4) Hit the Dark Green block on the Top Tray's right side to fill Slot 4's Dark Green Box, accepting that six Dark Greens will sit on the belt until later.
- 5) When the crates shift and the lower boxes suddenly ask for Pink, Purple, Blue, and Light Blue, hold the Blue and Orange tiles high in the center stack until a Blue receiver actually appears at the bottom.
- 6) Before releasing any 9-marble Purple block, confirm at least two Purple Boxes are ready below, or the belt overflows to the brim.
- 7) During the midgame, a White Box finally surfaces under Slot 3 or Slot 4, so let those three Whites from the very first move slide naturally into it to reclaim belt space.
- 8) In the messy late game, prioritize clearing the left side, and finally tap that opening Light Blue block only when two Light Blue Boxes are fully visible so nothing strands on a one-slot belt.
Level 123 Wooden Crate and Nine-Marble Trap
Welcome into this headache that is Marble Sort Level 123 .
This board looks simple with about two seconds until one realize this math is completely rigged against you.
this dominant shades east out from this gate sit Yellow, White, Light Green, and Dark Green.
But this colors are not the real problem.
this real issue sits this huge pair from wooden crates dominating the Top Tray .
those huge 2x2 wooden obstacles sit over this west plus east, funneling the entire opening strategy into one single, narrow center column.
one sit forced into play what this game gives one, plus what that gives one is a massive Conveyor Belt management problem.
Every move one make at this start from this board shall leave leftover marbles stranded on the belt.
If one choose this bad piece on this bad order, this track jams before one even break this first layer of bottom Boxes .
Level 123 Crate and Column Pattern
Let us talk about zzz exactly how this board is stacked.
one want into understand this layout before you start blindly tapping blocks.
on this upper rack , this lower line gives one five distinct pieces: gold, Light Blue, White, Dark Green, and Yellow.
Flanking this west plus east sit those huge wooden crates with the "X" on them.
Trapped between those crates sits a vertical stack of single blocks.
Reading from lower into upper, this middle lane is White, Light Green, Orange, and Blue.
one hold four columns of lower Boxes to fill.
Slot 1 (far west) needs White, then Light Green, then Yellow.
Slot 3 needs Light emerald, then Yellow, then White.
Slot 4 (far east) needs Dark emerald, then White, then Light Green.
this tiles on the Top Tray contain 9 marbles each.
If one choose that lower-middle ivory tile on the Top Tray , 9 White marbles drop.
this remaining 3 ivory spheres shall permanently clog the Conveyor track until another White Box reveals itself later.
This "remainder" mechanic sits this absolute core of Marble Sort Level 123 .
one hold into balance this leftover marbles, or you will fail.

Level 123 Surviving the Opening Jam
Do exactly this order into break this front lines without overwhelming the belt.
They shall right fill this ivory cases parked over top of Slot 1 and Slot 2.
one shall hold 3 ivory marbles left over on the Conveyor Belt .
Clearing that first ivory piece on this middle lane exposed one Light Green one right behind it.
Meanwhile, clearing Slot 1’s ivory case exposed a Light Green Box underneath it.
Slot 3 already holds a Light Green Box waiting on top.
Tapping this Light emerald block fills both of those Boxes .
one now hold 3 ivory plus 3 Light emerald spheres taking up space on your Conveyor Belt .

That Light Blue block from the beginning?
one atlast get into tap it in the late game.
Wait until two Light azure Boxes are fully visible.

Control this remainder, respect this wooden crates, plus you will beat Marble Sort Level 123 .
Frequently Asked Questions
What is the main trap to avoid in Level 123?
The biggest mistake is tapping colors that have no active bottom Box yet. They park on your Conveyor Belt and burn limited slots, so clear the shades that actually have receivers first.
How should I open Level 123?
Ignore the upper layers and aim at the bottom row of the Top Tray. Feed the colors that already have open boxes, then work upward once the lower lanes shift.
When does the midgame color change happen in Level 123?
After the opening boxes fall, the lower columns swap what they demand. Watch for the new shades and only pull blocks that match a box sitting at the front of a lower lane.
Any tip for finishing Level 123 clean?
Keep at least a few empty belt slots before poking mystery or hidden boxes. Feed a revealed color the moment it matches an active box, and fall back to visible marbles when the belt gets tight.
