Tips for Whack-a-Ghost on laptops:1. Change your settings so that you use the letters - this way your fingers are right in front of your screen.
2. Levels 1-3 are pretty straight-forward. Your fingers are over B-N-M for the bottom row, H-J-K for the middle row, and Y-U-I for the top row.
3. Levels 4-6 rotates. I now have to use my left hand and lay my arm across my keyboard. I position my fingers over U-J-N for the middle row. The bottom row is now Y-H-B and the top row is I-K-M. At this point, I'm not even looking at my keyboard. I look only at the screen and practice with my fingers.
4. Levels 7-9 rotates again. H-J-K is the middle row, just like levels 1-3. The first row is now Y-U-I (notice this row of keys is closest to the screen and the first row of graves is the closest to the keyboard). The last row is B-N-M (again, notice this row of keys is the farthest from the screen and the last row of graves is the farthest from the keyboard).
5. Levels 10-12 rotates yet again. I have to use my right hand the same way I used my left hand for levels 4-6. My middle row is N-J-U. The top row is B-H-Y and the bottom row is M-K-I.
6. The last round! Back to your original formation. This is where it gets a little glitchy sometimes (I don't know if anyone else has problems or if it's just me). The ghosts will pop up like they have in all the other rounds. But now you have skeletons to deal with. For the skeletons, you have to press the appropriate letter (you'll only use the bottom two rows: H-J-K and B-N-M). Be sure that if you have a skeleton and a ghost appear at the same time, get the skeleton out of the way first!
I hope that helps someone! I love Whack-a-Ghost and can always get at least 1000 points.
