困难

Block Out Level 20 is a two-room boss puzzle centered on a huge purple `5` block. Prepare the lower room, keep the green stem free, reduce the frame counters around the boss, and only then let the upper chamber resolve.

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.

困难

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.

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.

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 24 is a shared-corridor double-boss board with two framed `12` panels. Thin the right pillar ladder first, open the central shaft second, and let the upper boss fall before the lower one follows.
