Numbers will appear at the top and will move to the right.
Using these numbers, you must find combinations of two or three digits that sum to 10.
Select these numbers using the "keypad" or your keyboard (NEW!!!). You must click on the screen after clicking "Start".
The numbers you select will appear in the "selected" area. If the numbers you select sum to 10, then
they will be removed from the numbers up top.
Example: If the numbers up top are "337263894", then you can enter the following combinations:
"6,4" or "3,3,4" or "7,3" or "8,2" etc...
It doesn't matter what order you select the numbers.
The game is over when the numbers up top reach the far right side.
Scoring:
For every correct sum, you will receive (10 * level) points.
If you clear all the numbers, you will receive a bonus of (100 * level).
