Before every race starts, there is an ad shown of around 30 sec., Then after the race is finished another ad is shown of same time, and if we want to multiply the amount won from race, then again we have to see ad for that of same time that of other two........ So, we have to see 2-3 ads for just one race!! The total time for all ads around 3/4 time one race time!! ONE STAR FOR MAKING ASPHALT
