Apocollapse

Collapse is another of those stupidly simple, dangerously addictive, criminally overused casual concepts. Random colored blocks rise out of the floor, the player clicks groups of three or more of the same color to remove them, blocks must not reach ceiling. That's it, with the pace accelerating gradually.

I'm not aware of a multiplayer version of collapse. Here is mine, and it's called Apocollapse.

In Apocollapse, each player has his own stack of blocks being slowly pushed up out of the bottom of the screen. Except these blocks are cubes of multicolored ice, and the bottom of the screen is the polar sea. So in fact what you're spending your time destroying are those very topical glaciers, see?

As you destroy parts of your glacier, you release water. The larger the group of ice cubes you destroy with a single click, the more water you have - four cubes release half as much water as three cubes, five cubes release one and a half the amount of four cubes, and so on and forth. Yep, it's not physics logical, but it's gameplay logical.

Now, what happens with the water you release is that it flows through a sophisticated set of pipes straight into your opponent's playing field, raising his sea level and therefore the base height of his stack of ice. And when that pile of icecubes reaches the top of the game window, that player has to shamefuly admit a worldwide catastrophe and defeat.

If you wish for a longer game with an added twist, you can add in a combo meter. This means that destroying same colored groups in succession raises your multiplier factor (a factor that reverts back to x1 over time). This factor ties in to the rate at which excess water is drained from your side of the board: the higher the multiplier, the faster your drainage pumps are working, balancing the sea level against the flow of water from the opponent's side. So you have to balance between clicking on large groups irrespective of color, the aggresive stance, and clicking on groups of same-colored cubes, the defensive stance.
