Arrows
Craft special arrows to get large spark bonuses early. The starting "Rue" arrows do not require that many supplies to create. In later levels, create the "Primrose" and "Katniss" arrows to maintain your multiplier.
Upgrades
After increasing your coins and supplies, upgrade your pre-game spin bonuses and power-up skills. This will allow you to keep playing longer, and earn spark bonuses easier. This will in turn allow you to build larger spark bonuses and earn more coins quicker. For the spin bonuses, match district-specific bonuses with the materials required to upgrade your skills and arrows. By doing this you will gain vital supplies and increase your multipliers at the same time.
Various Tips and Tricks
Do go out of your way in order to pick up any materials that you find lying in the road, as these can be used to craft new arrows which boost your score in the archery sections, or improve your skills to help you perform better on every run.
Free coins!? hit the icon at the top-right hand corner of the main screen. From here, you can watch a few videos in exchange for 100 coins each time.
Improve your attributes first since these affect your performance and currency-gathering on every single run, not just when you encounter archery sections.
When you go online and start racing against other players make sure you've crafted your arrows. Having a solid selection of these will allow you to get a much bigger score during the shooting sections - and all things being equal, this can make the difference between the winners and the losers.
