It's time to rev up your Fantasy teams with a few pit-lane adjustments ahead of Sunday's Turkish Grand Prix. If you haven't picked one yet, it's not too late to get going - just follow our simple instructions.

- Choose three drivers for each race - one from Group A and two from Group B - plus a team.

- The top eight finishers in the race receive 10, 8, 6, 5, 4, 3, 2 and 1 fantasy point respectively plus there is a bonus point for any driver leading at any point during the race and a bonus point for completing the entire race.

The top three drivers in qualifying will earn 3, 2 and 1 point respectively meaning each driver can receive a maximum of 15 fantasy points during each race and each team can earn a maximum of 27 fantasy points per race.

AND NOW THE BEAUTY OF THE GAME:

- Each driver and constructor can be an active member of your team in no more than four races.

This means with 18 races scheduled you will have to use at least five of the elite seven Group A drivers at some point in the season and also at least nine of the 15 Group B drivers.

It also means that you have to pick five of the 11 F1 teams and herein lies the great dilemma of the game - who should I pick for each race?

Shall I pick all the big names early on to get to the top of the leaderboard? Which teams perform well on which tracks; which teams will improve as the season progresses.

The deadline to create a team for each race is 8am local time on the day of qualifying which means you must have your entries in by 6am GMT on Saturday morning.

FOUR FOR TURKEY:

The withdrawal of Super Aguri leaves only ten teams to choose from, and it would be madness not to stick with Ferrari if you reaped the rewards of their one-two podium finish in Spain.

Luca di Montezemolo's team are going for a hat-trick at the Otodrom, and Felipe Massa is the undisputed master of this young track.

For a second pick we recommend McLaren, who won in Turkey three years ago with Kimi Raikkonen behind the wheel. Heikki Kovalainen has recovered from his horror crash last week and will race.

If you're looking to switch your A driver this week, Raikkonen and Massa might seem the obvious choices, but how about a punt on McLaren's Lewis Hamilton.

Hamilton drove well in Turkey last year, only to be denied by a late puncture, and this just might be the week he returns to the top of the podium.

From the B group Red Bull's Mark Webber is a good bet. The Australian finished fifth in Spain, his best result since last July's European Grand Prix, and has been threatening to seriously challenge in a race for some time.

To keep him company how about Toyota's Jarno Trulli, who performed well on this track last year. The Italian was in fine form in Barcelona, and but for a breakdown in communications that cost him two places, would have finished sixth.

Toyota are unlikely to make the same mistake again, and will need little motivation to help Trulli to a decent result in Turkey.

Before every race we will give you the definitive guide of who is hot and who is not whilst within the game there is a Driver Performance Table - a stats tool showing you the top fantasy performers for each race of the season - and a Driver Distribution Table showing you how many managers are picking each driver.

So join up now, form a mini-league with friends, family or colleagues, watch your progress in your national league and you may find yourself at the top of the Grid!
