Please choose the correct ending to complete the given sentence: Computers and Electronics: [header] How to get a high score on subway surfers [title] Build up your multiplier. [step] The best way to get a higher score quicker is to improve your multiplier. When you first begin playing, your multiplier will be set at x1.

Ending1: This will help you hone your multiplier. You can use this to improve your performance and maintain your ability to land a high score. Ending2: If you aren't already, work your way up to an appropriate 1. Once you think you are ready, increase the x1 to 30x/per-second until you are level 18 (or over) by the end of the cycle. Ending3: However, your standard multiplier usually consists of x2. You will determine your score after you pass over the numbers. Ending4: Every time you beat a set of missions, you will level up, and your multiplier will permanently increase by one, up to x30. This means that your score will be 30 times what it would normally be if you have a full multiplier.
