Pick the badger you wish to bet on and then place a bet of the amount you want to risk. Once the race starts you will be able to slow opposing badgers by dropping cat bombs on them. Just click over the badger you wish to slow down. You only have 5 bombs though so use them wisely. If you find your badger is lagging behind a press of the spacebar will unleash a nitro boost if you have one. Nitrous are very expensive though so only use them if you have no other option. After the race if you win your bet will be doubled. If you lose you get nothing and forfeit the money placed on the bet. You will also be able to buy more bombs (up to a maximum of 5) or nitro boosts, but be warned items will cost more each time you buy one!
