Space Invaders

1. Scratch the YOUR SHOTS box to reveal up to 27 OUTER SPACE locations (letter/number combinations). Win $5 for each "Mystery Ship" symbol revealed in the YOUR SHOTS box.
2. For each letter/number combination in the YOUR SHOTS box, find the corresponding location on the OUTER SPACE GRID and scratch only that square. (For example, a YOUR SHOT at A1 is the top left-most corner square in the OUTER SPACE GRID; G7 is the lower right corner square in the OUTER SPACE GRID.)
3. If you completely uncover an entire horizontal row across in the OUTER SPACE GRID by using the YOUR SHOTS letter/number combinations, win the prize corresponding to that same row.
