Another thing that will affect your overall high score is the beginning safety bonuses. The bonuses compound upon each other as long as you keep completing the challenges. If you are on a winning streak with the safety bonus round, then the score that you earn will be compounded with the previous scores of the challenges that you have beaten in a row.
Watch out, though, because the challenge continues to get tougher and tougher as you add to your streak. You will have a shorter amount of time to complete them and you will have more to do. Figure out how far you can get and how many in a row you are capable of completing, and make a count of it, and use this to your advantage.
Then, go to the Dumb Dome, Freezerville and Drown Town and play them, and earn the bonuses until you get to your high point. Then go to the Dumbest of the Dumb, spend your ticket, and win the beginning safety bonus round. Then do the competition and get that extremely high score at the beginning of the level.. This will help to unlock any new character that you find it hard to get to, as well as increase your percentage on the global leaderboard.
Make sure to use all of your tokens each day. The reason for this is that if you have any tokens left over, that daily tokens bonus will not arrive, but if you have no tokens left over, then you will earn two tokens as a bonus the first time that you open the app that day (or when you cheat two tokens with the time lapse cheat).
See that red button? Pressing that will (as opposed to killing you) allow you to take the safety pledge, where you promise to be safe around trains. It doesn’t actually do anything within the game itself, but that’s the whole point of the Dumb Ways To Die campaign in the first place. Of course, if you don’t live in Melbourne, Australia, it won’t make much sense, but that’s the deal.
Want to score a new character without having to get a new high score? The only other way to get new characters is to unlock them via the bonus wheel at the end of Dumbest of the Dumb, so if you get really lucky, you can end up with a free new character for your use.
