Phones and computers

Dust Off is a dust brushing puzzle that plays in the browser on phones, tablets and computers, for one player.

You rub the dust from buried tablets to find sets of three matching glyphs in a row, column or diagonal. Brush strokes are limited, so you dab to peek at colours and clean only the lines that matter. Sets pay for better brushes and the next tablet, and reading all 20 tablets in full ends the game.

Tips

A dab costs only the brush width in strokes, 1.6 of the starting 300, while a cell reads only once 60 percent of its dust is gone, so dab first.
Two matching glyphs can be a decoy, since glyphs outside a set appear up to twice; dab the cell that would complete their line before cleaning anything.
Strokes refill on every tablet and unused ones are not kept, so press Done once the last set is clean; a full reading pays a bonus set.

What counts as a set in Dust Off?

Three equal glyphs in a row, column or diagonal. No other glyph appears more than twice on a tablet, so any three matching glyphs are a set. Tablets 1 to 6 are 3 by 3 with one set, 7 to 14 are 4 by 4 with two, and 15 to 20 are 5 by 5 with three.

How do I unlock the next tablet?

Read the current tablet in full, finding every set on it, then buy the next one in the workshop; the cost rises with each tablet. You can rub the same tablet again before buying, and every reading pays for the sets found, so repeat readings can fund brush upgrades.
