IMPORTANT NOTES BEFORE STARTING!
Lbpk.me stats are often VERY WRONG! I had 185 online wins at the time of starting this trophy, despite never having played online... Don't trust them!
1) Randomly playing 1 second levels will NOT
work at all/as efficiently as this method.
2) This is because each win obtained MUST
be from a totally unique level. Most of these '1 second' and '1 lap' tracks are copies of a copy and as such won't count!
3) It is suggested, but not necessary
to clear out all your hearted levels prior to beginning this.
This is handy as you can then heart each level you have completed to ensure you don't replay a level twice. Failing this pen and paper has always worked!
PLAYING THE LEVELS
1) Go to community and text search for DazzaFett
2) Select a level from the list (ideally at one and going up towards 30 at the end)
3) When selecting the level to play, you MUST
select "Play online!" and not "Play on our own". Playing on your own is considered a private match and not an Online Match as the trophy asks.
2) After completion of a level, ensure that you hit X a few times to look at the scoreboards. Both your time and your friends should be present in BOTH
Friends and Global scoreboards. If this is not the case it will not have counted as a win!
3) Vote to replay the same level as many times as needed so each person in your group can register a win on the level.
