Block Out Level 19 is a basement-first numeric board. Open the lower red, green, black, and white stack first, then flatten the giant `20/10` cyan carpet, and spend the yellow roof only after the middle has softened.

Block Out Level 21 is a triple-boss ladder. Break the framed `9` panel first, unwind the colorful middle strip second, and only then start shrinking the lower `16` and `18` panels.

困难

Block Out Level 18 is a double-frame puzzle around a cyan `14/11` pair. Peel the side ladders and counters first, keep the center blocks together until the rails are thinner, and finish through the green top route.

困难

Block Out Level 22 is a single giant boss-room puzzle around a purple `17` panel. Dismantle the checker roof first, let the huge boss panel start falling second, and clean up the late blue and pink pieces only after the lid is gone.

Block Out Level 17 is a framed-hinge numeric board. Trim the yellow roof first, unlock the green center frame second, and only then flatten the broad cyan slabs marked `19`, `18`, and `16`.

困难

Block Out Level 23 is a knot board with two framed lower boxes marked `11` and `8`. Use the top blue lane and right yellow gate to untie the curled center path, then let the two boss boxes fall once the knot is gone.
