DropSum v 2.0
We all like the math, right? Of course we do. Who could possibly forget the intoxicating aroma of graphing calculators, slide rules, complex algorithms... What? We don't all love math? Since when? Why wasn't I informed? Bah, no matter. Once you've spent a little quality time with the math-based block-dropping puzzle game DropSum v2.0, all of you math haters will be changing your tune.
This iteration is not so much a sequel as it is a major upgrade to the first DropSum. Just like the original, you drop numbers into a grid with the goal of linking together chains that add up to 9. As you make more and more successful chains, the individual numbers involved will change color from gray to blue to yellow to red. Finally they die, leaving an opening that can be filled in by other numbers, and giving you some breathing room. Fill the grid, and you're history.
DropSum version 2 has gotten itself a shiny new facelift, with cleaner graphics and a slightly less annoying soundtrack. It also awards you exploding tiles if you manage to clear ten red numbers in one move. But the biggest upgrade is the ability to rotate the entire board 90 degrees with the [left] and [right] arrow keys Knightfall style.
This last innovation makes a world of difference. In the original DropSum, numbers on the bottom row would turn essentially dead as it became less possible to make combinations that would reach them. Rotation largely fixes this problem, allowing you access to areas of the playing field that would have grown stagnant before. This innovation also makes the game considerably easier, which could be good if you're not looking to test your brain too much, but might be a big negative if you're looking for a big challenge.
Thus, in many ways this DropSum is what the original DropSum wanted to be when it grew up. It'll also give you a reason to once again cheer that most cherished of subjects, math.
