What should I clear first in Level 50?

Clear purple 4 first. The red target displays 0, so wait for the next populated target row instead of tapping red.

Are the gray cubes part of the opening color route?

They form the outer structural lattice. Follow the target row and clear gray only when its active phase appears.

Yes. The source reaches a clear WELL DONE screen after the final target groups are removed.

Open Level 50's gray-framed diamond from purple, follow the inner pink, teal, blue, green, cyan, and yellow route, and reach WELL DONE.

If the player asks you to sign in, open the video on YouTube instead.

Clear the exposed purple 4 group.
Ignore the red target count of 0 and follow the next populated row, beginning with pink and orange.
As the diamond re-presents automatically, take teal and peach from the inner side lane, then magenta and blue from the center opening.
Keep the gray outer lattice out of the buffer plan until gray is active; then clear the lower frame before continuing through green and cyan.
Clear the final yellow and lime groups from the outer diamond edge and wait for the source's WELL DONE reward screen.

Colors in this level:

Purple, Red, Pink, Orange, Teal, Peach, Magenta, Blue, Gray, Green, Cyan, Yellow, Lime

Trying to clear the red 0 target as if it contained cubes.
Tapping gray frame cubes before gray is the active target phase.
Continuing from the old diamond presentation after the next colored lane has opened behind the frame.

Start with purple 4; the red 0 needs no tap.
Let the diamond re-present automatically after each target refresh to expose pink, teal, blue, and green lanes.
Keep the buffer open for the late cyan, yellow, and lime groups, then wait for WELL DONE.

Board notes 5 details

Layout: The opening board is a tilted diamond lattice wrapped in gray structural cubes, with a multicolored inner core. Purple 4 is active; the red target shows 0 and is already empty, and the buffer row is empty.
Goal: Follow the refreshed pink, orange, teal, peach, magenta, blue, green, cyan, yellow, and lime phases while the gray frame releases the inner core.
Opening: Clear purple 4 first. Treat the red 0 as an empty target and wait for the next populated row.
Danger Zone: The gray outer frame surrounds the colored core and can hide the next accessible face. Do not spend a move on a structural gray cube until gray becomes the active target.
Mechanics: A gray-framed diamond re-presents automatically through its colored inner lanes; clearing a target group opens another face while the outer gray lattice remains as access-limiting structure. No manual swipe is introduced in the source.
