Tile-o-fall is a game mode that is relative to the Moving columns that features some new ideas. The tiles are falling down like a waterfall and move with equal speed. Figuratively speaking, the columns are individual water flows. They cannot be stopped by a tap, but the player may interrupt a flow by touching it; this means that all tiles found above the finger are stopped, but the tiles below fall down, exposing some content underneath the column (imagine you put a flap inside a vertical water pipe and see its walls). The underlying content consists of tiles as well; it can be static or dynamic, featuring elements that move horizontally. So, there are two layers in the game: a foreground, which moves vertically, and a background, which lies under the first layer and moves horizontally (or stands still). Here is the idea: the player breaks columns, trying to find useful tiles, which lie beneath. Once the tiles are aligned to each other, the roll call function is called and the player obtains some points if there are some suitable sequences. The codename for this mode is Tile-o-fall , but the tagline is Browse for tiles.

The following screenshot shows a simple version of the Tile-o-fall mode, there are four rows, elements moving evenly, and a multitouch input:

The game can use both single-touch (coherent) and multitouch control of columns; the latter is of course more exciting.

Potentially, the game can hold more than two layers; the player must search through this stack to find something useful. To motivate him, each layer should have special features. For instance, the second layer can include only green and red tiles; the third one, only blue and green; the fourth, green, yellow, and red; and so on. It is better to use coherent control for such a variant of the game.

It is worth mentioning that the Tile-o-fall mode can be developed with a static foreground, without moving columns. In this case, the player simply browses for correct matches, lifting some vertical lines of tiles a little.
