It’s hard enough creating one substantial game in a series, let alone a franchise that holds up over several iterations. Sprinkle is one example of how to do it right. The original Sprinkle was a surprise and a delight, and Sprinkle Jr. was entertaining, though it sat much better with my 8-year-old son who actually played it through at least three times. Now we have Sprinkle Islands ($1.99), and it looks to be everything the original Sprinkle was to a grander scale. My only grumble so far is that it didn’t do away with the need to play each world completely through to get to the next one.
