Level 712 takes an 11-cover to 0 with a yellow vertical at the left yellow gate, then clears concrete color groups around two 9-marked obstacles.

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

Clear small red, pink and blue pieces from the bottom chamber through their nearest matching gates.
Turn the lower yellow and green L shapes toward side gates while leaving the center column open.
Remove short purple and red pieces until the cover reaches 3, without parking a long piece under its left edge.
Send another compact block out, then align the yellow vertical with the left yellow gate at cover 1.
Exit that yellow vertical to change the cover from 1 to 0, then pull the newly exposed long framed yellow horizontal left through the left yellow gate.
Follow with the long red horizontal and the pink horizontal below it so neither seals the central turn.
Work the revealed left block as orange columns around the two brown 9 groups, then the blue/cyan stack and adjacent yellow column.
Unwind the right purple/yellow upper bend, red-green middle bend and orange-yellow lower bend one at a time, restoring center after each exit.
Alternate the remaining pink and green L shapes with cyan verticals, then remove late red and yellow bars to free the green cluster.
Exit green verticals and L shapes, then send the final green horizontal through the left green gate for the PERFECT clear.

Colors in this level:

Blue, Cyan, Green, Orange, Pink, Purple, Red, Yellow

Dragging a framed right-hand piece across center before the 9-marked left area has been reduced.
Using the center column as parking while the yellow vertical still needs the left gate.

Keep the central vertical lane empty until the framed right-hand shapes are ready to leave.
After the reveal, pull the new long framed yellow horizontal left first.

Board notes 5 details

Layout: A hedge-edged 11-cover hides the upper board while red, yellow, pink, purple, blue and green pieces fill the exposed bottom pocket.
Goal: Use eleven lower exits to reveal two 9-marked groups, orange columns, a blue/cyan stack and framed right-hand bends, then preserve center space for each color wave.
Opening: Clear the bottom red bars, pink bends and right-side blue pieces before turning the yellow and green L shapes toward their side gates.
Danger Zone: Long framed pieces crossing center too early remove the turning room needed beside the two upper-left 9-marked obstacles.
Mechanics: A single 11-count cover reveals the main board; the exact zeroing move is a yellow vertical through the left yellow gate.
