Few boards are this rigid about your first moves. You're looking at a cross-shaped tray full of lime green, orange and light blue, and it seems simple. It isn't. Three Panels sit on the left, top and right outer edges, each stamped 3, and you can't reach the wings under them until you've cleared three Boxes.
Your front Boxes want Lime Green on the far left, Orange beside it, and Light Blue in both right columns. But the tray's reachable line is Red, Orange and Lime Green — and the Light Blue you need is hidden behind that front-left Red and the Dark Blue blocks in the centre.
Marble Sort Level 102 Walkthrough
Digging for the Light Blue in a panic fills your belt with dead colours. The board hands you an easy Lime Green and Orange match to lull you, then makes you route around a blockage for the third clear. The maroon and pink in the second and third rows are bait — there's no matching Box anywhere near the front.
You need exactly three clears to blow the wings open, and one of them costs a deliberate belt sacrifice.
How to Beat Marble Sort Level 102 — Step-by-Step
Crack the 3-clear countdown
- Send the Lime Green on the front right into the far-left Lime Green Box — one down.
- Send the Orange front and centre into the second column's Orange Box — two down.
- Your front Boxes are now Blue, Lime Green, Light Blue and Light Blue. You need Light Blue.
- Sacrifice the front-left Red to the belt — it's the price of reaching the Light Blue behind it.
- Tap the now-exposed Light Blue to clear one of the right-side Boxes — three clears, Panels unlock.
Manage the midgame jam
- The wings reveal Purple (left), Light Blue (top) and White (right), while your belt still holds that Red.
- Don't touch the deep Pink or Maroon — their Boxes are buried in the back rows and they'll jam you.
- Grab the secondary Lime Green behind the first wave for the second column's new Box.
- Hold the Purple from the left wing until the Purple Box in column one reaches the front.
- Clear the remaining Light Blue with the marble under the top Panel, and never drop three unmatched colours in a row.
Clean up the back rows
- The Maroon and Pink you avoided finally get matching Boxes on the front line.
- Clear the Blue Boxes with the deep centre marbles.
- Feed the Red you sacrificed way back into its Box when it appears in column three.
- Empty the wings and sweep the final deep-row blocks to win.
Tips & tricks
- The Red sacrifice is the whole trick — one wasted slot buys you the Light Blue that pops the Panels.
- Leave Pink and Maroon until their Boxes rotate up, no matter how tempting they look.
- Keep the belt to one off-colour at a time when you have to dig.
Common mistakes
- Tapping deep Pink or Maroon in the midgame, jamming the belt with colours whose Boxes are back-row only.
- Refusing the Red sacrifice and never reaching the Light Blue, so the Panels never unlock.
