Flowers need to be matched to build up an energy meter, and it has to be done before all of the petals fall off. Blocks of fire need to be snuffed out as they spread. Soon, you'll encounter variations that do away with color changing in favor of something else entirely. Even at this most basic configuration, you'll be given some obstacles such as fog, ice blocks and locks, and making matches near them clears things up. The most common one is making matches to change the underlying board tiles to blue, and the target object only appears once the whole board is that color. However, the game throws plenty of puzzle variations at the player. The main objective is to move the target object, which is usually a piece of something much bigger, to the bottom of the playfield before time runs out. Matching six or more produces balls of energy that randomly destroy other objects on the board. Matching three is necessary to make them disappear, so other objects can cascade down to fill up the empty spaces. The most prominent one is a match-three variant, where you trace out a chain of similar objects that connect to one another. Again, none of this is really necessary for a puzzle game, but it is a nice touch nonetheless. Even with the use of mostly still images, the game bookends each of the campaign's 17 chapters with fully voiced cut scenes. The story is pretty much a riff of Jules Verne's Journey to the Center of the Earth, and while the tale isn't put to great use, the team has to be applauded for pushing the narrative at every opportunity. She's alone and determined to find a way back home. When Jules comes to, she finds herself at the center of the Earth with no one else in sight. It doesn't take long for the journey to go awry, as the ship is pulled into a maelstrom and sucked into a whirlpool. You play as Jules, a young woman who is sailing aboard a vessel named the Celestia from Liverpool to New York.

Though puzzle games don't necessarily need one, Azkend 2 comes with a story. When compared to all of those games, Azkend 2: The World Beneath did the one thing that made sense on paper: throw everything at the player and hope it sticks. The duo of Sparkle Unleashed and Sparkle 2 took the Zuma approach and did their match-three thing with moving marble lines.

Frozen Free Fall: Snowball Fight took the very successful mobile game's levels and added a local multiplayer versus mode. Both Gems of War and Marvel Puzzle Quest: Dark Reign added a heavy RPG component to their combative iterations. Even though the match-three puzzle type isn't as crowded on the Xbox One as it was on the Xbox 360, you still need to do something different in order to stand out.
