What is Sugar Shuttle?
Sugar Shuttle is a colour-matching puzzle where a little shuttle line loops around a mosaic made of candies, and every passenger is a gumdrop with an appetite for one colour. As a rider rolls past each row and column, it nibbles the outermost candy there, but only when the colours match, and steps off once its bites are spent. Riders that finish a loop still hungry wait on a bench with as few as 2 seats, so the real puzzle is choosing who boards next. Mosaics grow from 49 candies to 400 across 30 levels.
