## How to Play:

LEFT/RIGHT arrow or J/L keys: to move the dropping apples.
Spacebar: to drop the apple.

How to get points: You get points if the sum of two apples' numbers is greater than or equal to the green apple's number in the same row. You get more points (and a STAR!) if the sum is exactly EQUAL TO the green apple's number.

There are three types of apples:

• Red apple: Use UP/DOWN arrow or i/k keys to change the number within 0 and 9.
• Yellow apple: Use UP/DOWN arrow or i/k keys to change the number randomly within 0 and 19.
• Rotten apple: The number is fixed.

## Tips on Getting Higher Score:

• You get the most points (and a STAR!) if the sum is exactly EQUAL TO the green apple's number.
• If for any reason you can't get the sum to equal the green apple's number, try to make the sum as close to the green apple's number as possible.
