The premise is hard to describe fully, yet incredibly simple once you get your hands on the game. Within a couple on minutes you'll find yourself devising all manner of strategies to get pieces into place. However, you're on a timer and, as we all know, timers make people do stupid things. Thankfully, gameplay is forgiving enough that a couple of slides will get you out of any situation. It's simple, but something you can easily steal away a few minutes of your day to play.
Just to gum up the works, items - like candy corn or UFOs - will slide into the bin rather than tiles. Pushing similar items (like two smiling jack-o-lanterns) into each other stacks them, while combining matching sets (candy corn and a trick-or-treat bag, for example) nets point and time bonuses. You can also slide the items into the bin to scaffold other pieces of the puzzle into place. However, items can overstay their welcome and disrupt your strategy by removing nearby tiles.
