Draw a loop around the gold dot, leaving silvers outside. Quick — none of them stop moving.
Several dots bounce around the screen. One is gold, the rest are silver. Drag your finger across the screen to draw an enclosing line — when you lift your finger, the line closes into a loop.
You capture a dot if your loop encloses it. To score, your loop must enclose the gold dot and only the gold dot — no silver dots inside.
A clean capture scores you a point. The dots reset with one more silver added and slightly faster speed.
A miss — either a loop that doesn't catch the gold, or one that catches a silver — costs you three seconds off the clock.
The dots keep moving while you draw, so you have to anticipate where the gold will be when you close the loop. A loop that's too short to enclose anything is discarded silently with no penalty.
You have 60 seconds. Goal: capture the most gold dots.
Wait for the gold dot to drift to a corner before drawing. Corners give you two walls on which the silvers can't crowd you. A gold dot floating alone in a corner with all silvers clustered on the opposite side is the easiest capture you'll ever get — be patient enough to wait for those moments.
Draw fast, close fast. The longer your finger is on the screen, the more the silvers can drift into your planned loop. Spend the planning time before you start drawing, not during. Trace the smallest loop that just clears the gold; don't make grand gestures that take long to complete.
Watch the silver dots' headings, not just their positions. A silver dot moving away from the gold is safe to ignore; one moving toward the gold is your real enemy. Plan your loop to close before that silver enters the danger zone, not after you see it cross in.
