Phones and computers

Broom Swarm is an auto-shooter survival game that plays in the browser on phones, tablets and computers, for one player.

A janitor robot survives five minutes of dust bunnies with up to six of eight cleaning tools that fire on their own. Clumps join at 0:40, sprinters at 1:30 and big fluffs at 2:30, and dust on swept floor moves at just over half speed. Tools level up to 5, and beating the Dust King opens the Gym, then the Cafeteria.

Tips

Sweep in loops, not straight lines. Dust crossing floor you have already cleaned moves at 55% speed, so a clean ring around you slows every sprinter that comes.
Sturdy shell is also a heal: each level adds 25 to your maximum health and restores 25 at once, which is worth having when the big fluffs start at 2:30.
The Dust King keeps calling bunnies while fewer than 120 dust are on screen, so clearing its escort only invites more; put your damage on the King itself.

How many tools can the robot carry?

Up to six of the eight, each levelling to 5. Once six are held, the level-up cards offer only levels for tools you have and the five passives. A second level-up earned while cards are already up waits its turn, and the Duster swipes behind you as well from level 3.

How do you unlock the Gym and the Cafeteria?

Sweep away the Dust King at five minutes in the Hallway and the Gym opens; win there and the Cafeteria opens. Each arena has its own floor colours, and the ‹ › arrows on the start card choose which one to play. The end card also reports how much of the floor you swept.
