World Series

The multiplayer World Series competition is available to players of Asphalt 8: Airborne. World Series races can be played without limit with any car the player chooses. The goal is to achieve Win Streaks, which will be rewarded with credits, upgrades or nitro starter boosts. Whenever the player loses, achieves 9 wins in a row, quits a race or is otherwise disconnected for server/ application malfunction, his streak ends. Exiting multiplayer mode after a successfully finished race does not result in losing the streak, however the possible 7-streak (random D-class upgrade/ credits) and 9-streak (random C-class upgrade/ nitro starter boost) rewards may be automatically converted to credit rewards in case of a 7-streak and in a nitro starter boost in case of a 9-streak upon re-entering multiplayer mode. "Winning" does not necessarily mean achieving first place, rather landing a place on the podium – placing first, second or third.

Your opponents will be selected depending on your car's upgrade level, so if you choose to race with a Class A car, you will not race players with a Class D car. However you might face opponents with a low ranking Class S car, or with a high ranking Class B car.

At the beginning of the race, you will be able to vote for a Race Mode: Classic, Elimination, or Infected; one of three randomly proposed tracks, and the number of laps (1-3). As of August 8th 2015, when Tenerife was released for multiplayer, all locations are now available for multiplayer. The vote is democratic, however in ties the first value established remains. The voting will not wait for everybody, after a certain time, the race starts even if you have not yet voted.

Rating

After the race, you will be presented with the results. The second column is the rating, which persists between multiplayer races and is increased or decreased depending on your result, followed by an indicator if it was increased or decreased, and by how much. Players who get disconnected or leave lose 10 points.

It seems everyone starts with a rating of 1000 at the first multiplayer race.

The distribution of the rating points after a race is unclear. It can happen that someone with a high rating such as 1300 positions fourth, and loses 6 points, while someone with a medium-high rating such as 1100 positions third and wins 3 points, and someone with a rating of 980 positions sixth and still gains one point.If you face an opponent with a higher rating than you,winning the race will give a bigger rating increasing.

Also it seems the rating has no influence on or relation with any other game element. Potentially the starting position depends on your rating.

Rewards

Rewards are attributed after a consecutive serie of wins*, additionally to the credits you earn for your position in the race (first place between  700 and  1,000 Credits). The reward is independent of your multiplayer experience level or your stars level.

Number of wins*	3	5	7	9
Reward	1,250	2,500	Class D Upgrade (Acc. / Nitro / Handl.)	Class C Upgrade (Acc.)

*be among the first three

It is not yet clear if the upgrades depend on your personal progress (wether its useful to you or not) or if it is complete random. Also there seems change when you leave the World Series after 5 wins and re-enter, you get  5,000 credits rather than an upgrade after 7 races.

World Series vs Farming

If you have unlocked Seson 9, it is more efficient to buy a double credits boost, farm a track of season 9 and to buy the upgrade than to get an upgrade via multiplayer. The most expensive Class C Acceleration Upgrade is currently Felino cB7 level 4 to 5, and costs  81,250 credits, which can be farmed in eight to nine Season 9 races, and will take less time. If you are looking for fun races rather than advance your level, multiplayer is your thing.
