Key is to spell TIME. Letters rotate so you need to make sure the one you need is lit prior to shooting it. Lighting TIME enables SNAIL TIME
Complete top 12345 lanes prior to completing TIME, so the playfield is at least 2X. Best to try to get to 3X or 4X before completing TIME.
Add time by shooting the "1" rollover (10 seconds) or the lit inlane (5 seconds).
Fan of Jack White/The Raconteurs? The tempo of Snail Time is very similar to Steady As She Goes!
During "snail time", lift flippers out of the way to drain the ball ASAP. This stops the clock until the ball hits a top rollover switch.
