Place a portal on a white panel, then launch a dart through the chamber. Catch it lower to build speed, redirect it through glowing rings and stick the bullseye. Hold to slow time while aiming, and use the predicted path to plan your next move. Master 20 test chambers with bounce pads, fans, glass and timed lasers, then unlock 100 Proving Grounds challenges.
Cleared chambers, collected rings, tried levels, best speed/time/portal records and sound settings stay in this browser on this device. An unfinished launch restarts after closing the game. Clearing site data removes progress; it does not sync between devices.
Content: Stylized test chambers, flying darts, lasers and breaking glass; no depicted injury.. Browser privacy settings can affect saving.
