WallBall

About

JezzBall is a 1992 Microsoft Windows video game in which the player captures parts of a rectangular space by drawing walls that must not be touched by bouncing balls while under construction; it shares similarities with the 1981 arcade game Qix. WallBall is a browser-based area-capture game in the style of JezzBall, part of "The Plainsight Collection" -- a set of games distributed as bookmarklets disguised as ads so they can be played surreptitiously at work. Left-clicks build wall segments two at a time, right-clicks change the build direction, and bouncing balls can interrupt construction; reaching 75% board coverage advances to the next level.

How it differs from the original

Like JezzBall, WallBall is about walling off sections of a play area while avoiding bouncing balls, but it's delivered as a disguised browser bookmarklet rather than a standalone desktop game, and allows a limited number of ball interruptions per level (matching the number of balls present) rather than an instant game-over.

Getting started

WallBall can be played directly from the project's landing page, or installed as a bookmarklet that injects the game into most non-GitHub web pages as a fake ad; clicking the bookmarklet (or pressing the hidden 'b' key while the game is minimized) brings it up on any site serving third-party ads.

Additional notes

Quirk

Some ad blockers prevent the bookmarklet version from loading; disabling filtering for that site may be needed.
