Pool Patroller

The reflecting pool is turning green — and you're the only patroller on duty.

Drag your finger across the water to scrub away the spreading algae. The longer you survive, the faster it grows back, so keep those hands moving. Your score is simply how many seconds you last.

But you're not alone out there. Canada geese paddle across the pool and leave stubborn fouled spots that resist your brush — chase them off with a swipe before they make a mess. And as you survive, you'll earn power-ups to turn the tide:

Hydrogen-peroxide balloons that blast the algae clear
A timed big brush that triples your reach
An orange cleanup crew that wades in and scrubs alongside you
