How to Hack Scribble Rider

New to this? Start with our general guide to hacking Android games.

Scribble Rider is Voodoo’s draw-your-own-wheels racer, past 100 million downloads on Google Play. The coins on the track go into a counter in the top right corner, and the game writes that counter to its playerprefs file as a key called coins. My wheels kept missing them, so I still had 0 after two races. One edit in CheatDroid made it 999,999.

1. 1

   Start Scribble Rider and finish the first race, so the game has written its save. The coin counter is in the top right corner of the start screen.

2. 2

   Open CheatDroid, allow root, and tap Scribble Rider in the app list. It has one file under Shared preferences, com.tapped.drawrider.v2.playerprefs.xml; open it and tap Force stop if CheatDroid asks.

   

3. 3

   Search for coins. One key comes up, an int; tap it, type 999999 and tap Save.

   

4. 4

   Start the game again. The counter reads 999999.

5. 5

   Race on. My next race picked up 5 coins and the counter went to 1000004, which is what the game still showed after a restart.

   

What else I found

• The key is there from the first start, at 0, so you don’t need any coins of your own first.
• The other riders are the computer. A race started with them in airplane mode.
• Tested on version 3.9.6.
