General Neptune Bomb tips:

The rippa thing about this puzzle is that you can't mess it up.

With a bit of memory and determination - almost everyone

should be able to solve it... I hope.

If you haven't worked it out yet, this bomb is a four

level, randomly generated, "concentration" puzzle.

For the first level you must match pairs of symbols.

For the second level you must match symbols in groups of threes.

For the third level you must match symbols in groups of fours.

For the fourth level you must match symbols in groups of sixes

Keep trying and guessing until you work it out.

Hope this helps! Good Luck mate!
