Step-by-step solution
- 1) Tap the Red block in the middle-right spot of the Top Tray front line to empty the Red Box in column two and expose an Orange behind it.
- 2) Leave that fresh Orange alone for one second instead of grabbing it early.
- 3) Take the Dark Blue block at the far-right edge and drop it, emptying the fourth-column Dark Blue Box and unmasking another Orange.
- 4) With two Oranges now visible and two Orange boxes active, tap both Orange blocks to drain those receivers.
- 5) Then tap the Green block and follow it with the Light Pink block at the front of the Top Tray to clear their pair of boxes and start the chain.
- 6) Once the Mystery Boxes in columns two and four switch on, hold still until their question marks dissolve into real colors.
- 7) If a needed color is sealed in the blue Tunnel marked with a 3, clear the blocks sitting directly in front of it so it opens up.
- 8) Finish by matching the Light Blue blocks to the deep boxes in column three, and only drop the top-left Yellow block once everything else is cleared.
