Spooky Spirits: Puzzle Drop's premise has you going all around the world trying to recapture escaped spirits that a bumbling duo of spooks have accidentally let loose from the afterlife. It seems that the only way to capture these ghosts (who are for some reason stuck in multi-colored blocks) is to connect their block with like-colored blocks. Doing so releases the spirit and sends them back from whence they came. Ghost-blocks are fairly rare though, most tiles that you will send down from the sky will just be a solid color, and when those colors land and are adjacent to other similarly-colored tiles, they connect and become part of one larger (and usually oddly-shaped) block. When a ghost of that color touches the larger block, the entire chain of tiles go away causing the pile to collapse some. This is good since the bottom of the pile is constantly being raised by a new layer of tiles and your goal, for the most part, is to stay alive as long as possible.
It's the dropping of your tiles and ghosts that makes Spooky Spirits really interesting. On the top of the screen are two rows of tiles. You have a selector highlighting two adjacent tiles on the bottom row and a flick of your finger will send that pair downwards to the playing area. You can also move the selector left and right to change which pair you want to drop, but you can also use your finger to swap the two tiles you have selected. The idea is to move the perfect pair of colors to an area where dropping them will either create better connected blocks, or destroy as many blocks as possible (provided there is a ghost in one of your selected tiles). The game sounds a lot more complicated than it really is, but then again, even when you get a feel for the game and it's controls, it is still a really tough experience.
In Panic Mode, you are trying to fill a gauge before the tiles reach the top of the screen, and part of the strategy of this level involves creating large same-colored blocks so that their destruction will bring you a ton of points, but still managing to not make the pile so big that you will lose too quickly. Eternity Mode is Panic Mode, but without the gauge. Basically, here you just try and survive in that level as long as possible, and new locations are unlocked as you unlock them in Panic Mode.
Meanwhile, the game's third option, Puzzle Mode, presents you with a series of pre-set boards and a few tiles to drop from above. You can swap and rearrange the soon-to-drop tiles as much as you want, before actually letting them fall, but you have only a specific number of drops to use in order to clear the board. Most tile-swapping puzzle fans should be pretty familiar with this idea already and know what to expect in this department.
