How do you beat the voltorb flip game on heartgold and soulsilver? its so hard!!!
Here are some tips.
When a row or column has zero voltorbs shown, just flip everything in that row.
Mark every square with what it could possibly be.
Make educated guesses based on the marks, it is mostly about luck.
For every correct flip, mark the other squares in the row and column it was in to match what you found.
