Marbles is also a classic internet java game. You are given a grid (generally 10X7) filled with different colored marbles (usually 5 colors) and told to clear the grid by clicking on marbles of the same color that are touching. When this is done, the remaining marbles will fill the created hole. You continue to play until there are no like colored marbles touching such that none can be removed.

The standard scoring is N(N-1) for the number of marbles you clear in one turn. There is usually a bonus for having 5>=marbles at the end.

The scoring (for those of us not mathematically inclined) tends to go like this:

``` Number of marbles cleared               Points
2                             2
3                             6
4                            12
5                            20
6                            30
7                            42
8                            56
9                            72
10                            90
.                             .
.                             .
.                             .
70                          4930*
```

*if you clear all marbles, there is a 100 point bonus, which makes it 4930 instead of 4830. The bonuses break down like this:

```    Marbles Left              Bonus Points
4                         20
3                         40
2                         60
1                         80
0                        100```
