What is the safest way to identify groups on Level 4?

Match color together with engraving: pink knot, orange flower, red spiral, light-cyan wheel, and dark-blue dots are distinct group markers.

Do I need the buffer on Cube Tap Sort Level 4?

No occupied buffer cell is shown in the video; follow the active patterns directly and leave the four cells empty.

Cube Tap Sort level guide

medium 6 colors

Follow the patterned groups across the compact two-block board: pink, orange flower, red spiral, light-cyan wheel, then dark-blue dots.

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

Confirm the opening pink/magenta 4 and dark-blue 4 targets and the four empty buffer cells.
Release the exposed pink/magenta patterned cubes until its target checks off.
Continue through the orange flower group and then the red spiral group as their targets appear.
Clear the light-cyan wheel group, then finish the dark-blue dotted/star group from the remaining faces.
Wait for the final target checkmarks and WELL DONE screen.

Colors in this level:

Pink, Magenta, Orange, Red, Cyan, Blue

Using color alone and confusing the neighboring patterned groups on the two-block face.
Reaching for a covered cube or filling a buffer cell when the demonstrated route keeps all four cells empty.

Use both color and engraving to distinguish the pink, orange, red, cyan, and blue groups.
Clear the currently active pattern before switching attention to the next target.
Leave all four buffer cells empty as shown in the verified solve.

Board notes 5 details

Layout: The board opens as two adjoining 3D blocks with patterned faces. Pink/magenta and dark-blue target groups both show 4, and four buffer cells are empty.
Goal: Clear the active patterned groups as the target row advances from pink/magenta through orange flower and red spiral to light-cyan and dark-blue.
Opening: Release the exposed pink/magenta pattern first, then use the newly visible orange flower and red spiral faces before finishing the cyan and blue groups.
Danger Zone: No buffer cell is occupied in the video, and no loss or booster state is shown. Treat the engravings as group identifiers and do not reach through covered layers.
Mechanics: The level tests recognition of color-plus-pattern groups across two adjoining blocks; it does not demonstrate a new control beyond the established tap release.
