Number Ball: Rules

Aim

To get more marks than the computer.

Control

There are 4 types of blocks:

	Positive marks that can be chosen.
	Negative marks that can be chosen.
	Positive marks that cannot be chosen.
	Negative marks that cannot be chosen.

Every time you have to choose one block in the row with red/green blocks and you can get the score indicated. Then the block will disappear, and then the computer will choose a block in that column.

The game continues in the same way until you or the computer can have no more block to choose.
