Apologies if this has already been covered. I didn't see it mentioned anywhere.

i was able to collect my fifty crystals pretty quickly by 1) building a lot of Crystal Casinos and then 2) using a bunch of "Collect Immediately" scrolls in quick succession.

Using a "Collect Immediately" scroll causes about 80 percent of your Crystal Casinos to emit a crystal - even if they're nowhere near their "dollar sign" time. So build a bunch of Crystal Casinos (wait until they've completed building), collect a bunch of "Collect Immediately" scrolls (they're only three pearls apiece, so they're cheap), then use those scrolls one after another a minute or so apart to collect a lot of crystals quickly.
