Unity was originally invented in Japan 1985 as "Chain Shot!" by Kuniaki Moribe. After that it has spread all over the world with names such as SameGame, TumeGame, KomeGame, MameGame, DebaGame, TileFall, Cabeem, MaciGame, GD-BMD etc.

The idea is to clear the whole playing area by removing tiles in groups. The more tiles you remove at the same time, the more points you get. The trick is that the scoring system is exponential:

1 tile - cannot be removed
2 tiles - (2-2) ** 2 == 0 points
3 tiles - (3-2) ** 2 == 1
4 tiles - (4-2) ** 2 == 4
5 tiles - (5-2) ** 2 == 9
6 tiles - (6-2) ** 2 == 16
7 tiles - (7-2) ** 2 == 25
8 tiles - (8-2) ** 2 == 36
9 tiles - (9-2) ** 2 == 49
10 tiles - (10-2) ** 2 == 64
11 tiles - (11-2) ** 2 == 81
12 tiles - (12-2) ** 2 == 100
13 tiles - (13-2) ** 2 == 121
14 tiles - (14-2) ** 2 == 144
15 tiles - (15-2) ** 2 == 169
...
n tiles - (n-2) ** 2 == Lots of points

Tip: As you can see you should remove small groups in order to
create larger groups. When the group is big enough even just one
more tile will make a big difference.

When you remove tiles, the space will be filled by tiles above
falling down. Empty columns will be filled by sliding remaining
columns to left. If you manage to clear the whole field, you will
get 1000 points as a bonus and go to next level.
