How to play Block Blast

Fit wooden rune shapes into an 8×8 board. This Block Blast-style puzzle gives you three pieces at a time, including beams, squares and familiar L, T and zigzag shapes. Choose their order carefully: a new tray arrives only after all three have been placed.

How do rows and columns clear?

Every filled row and column disappears after a placement, including intersecting lines. Each placed block earns one point. Clearing lines adds 10 times the square of the number of lines: 10 for one, 40 for two and 90 for three. Empty space remains where lines clear; blocks do not fall.

When does a run end?

The run ends when none of the shapes left in the tray can fit anywhere. A blocked shape can become usable after another piece clears a line, so check all your options. Play again starts with an empty board and three fresh shapes. Your best score and unfinished board stay in this browser when storage and safe saving are available.

Make room for the next rune.

Select a shape, then tap the top-left corner of its rectangular footprint on the board. The whole shape must fit into empty cells. Shapes cannot rotate.

Fill a row or column to clear it. Earn one point per placed block plus 10 × lines × lines per placement. Two lines add 40 points, three add 90.

Use all three pieces for a fresh tray. The run ends only when none of your remaining shapes fits. Your best score and unfinished board save on this browser when storage and safe saving are available.

Keyboard: 1–3 selects, arrows move focus, Enter or Space places, Escape cancels. Close this help panel and press Resume if you paused a run.
