Bonus races are races with twists to it. The two additions to a bonus race that will be present no matter what are:
- Ratings for everyone (all players will get more ratings regardless of their position in the end)
- Bonus coins (more coins for all)
The third bonus slot can vary. The ones that I have encountered are:
- Zombies: All players will appear as zombies and only rifle power-up is available
- Magnets: Only magnet power-up is available
- Big heads: All player's head size will increase, but I'm not sure if this will have any effect on the speed of the players.
- Small animals: All player's avatar size will decrease, but trap sizes and power-up sizes remain constant. Players' running speed will increase.
- Sawblades: Only sawblade power-up is available.
