Hollow Blocks

Stack the building materials, clear the lines and build the house next door, one floor every ten lines. Hollow Blocks is the classic falling-block puzzle set on a sunny construction site in a Filipino barangay, in full 3D.

• House: endless play with tools from toolboxes: the Hammer, Cement, Crane, Roller and Snack.

• Classic, Deadline (40 lines), Storm (mud rising from below), Race (2 minutes) and the Daily, the same pieces for everyone each day.

• Projects: 30 contracts across 6 barangays, with brownouts, wind, earthquakes, cracked blocks and the City Inspector.

• Versus: send mud to six rivals in the Barangay League. Head to Head: two players on one keyboard.

• Training: lessons in T-spins, combos and finesse from Kapatas, the foreman.

• A shop of block skins, outfits and site themes, plus ranks, medals and a weekly event.

Clear four lines at once for a BAYANIHAN, the whole neighbourhood pitching in!
