Race for Kicks is an OWOOT racing event. This means you must remain on or over the asphalt/dirt/ice at all times (one wheel on or over the track) and you must execute all stunts. You may not use shortcuts or skip stunts in any way.
Replays are checked by using the F3 view, rotating the viewport upwards to the maximum and then clockwise (to the right) three times. No change is to be made to the zoom level. If at any point, from this view, none of the four wheels is at least in contact with the main material of the track (asphalt, dirt or ice), then the replay is invalid. Even if it is apparent that there would be no pixel overlap, the replay is valid as long as there is contact. The reason is that overlap is an abstract concept (as the background pixel really does not exist) and in curves and chicanes, it may not be clearly defined. Other rotations or zoom levels may give different results, but these are not to be taken into account. Still, it is recommended that you avoid any situation that may produce doubts.
Each track element usually has an intuitively defined stunt-action. For example, when facing a loop, you're supposed to roll through it, not jump off. When you get to a tunnel, it is understood you must go through it, not over it or on top of it. If you get to a slalom, you're expected to dodge the stones, not go straight through them. This is usually described as "following the yellow/white lines", although this is rather vague (for example, it's clear that there is no violation in rolling inside a pipe).
A speed-up is something you do that is clearly going to improve your lap time, but consists of more than just driving, rather exploiting the game's unreal physics. In many tournaments, this is not allowed. In Race for Kicks, speed-ups are allowed as long as you stick to the OWOOT rules. For instance, when driving on a highway, you may use the boulevard division to jump and accelerate, but the bolevard division is not considered part of the track (asphalt), so at least one wheel must remain partially on or over the asphalt for the replay to be valid. Also, at a pipe entrance, you may use the side to jump in, but the replay will be invalid if the car is seen to be fully off the asphalt. Jumping at the start of banked roads is OK, but make sure you don't fly over the grass if there's a banked corner just after the straightway-to-banked-road transition.
You are allowed to use replay handling. If you did not use it, you can specify that when uploading your replay and this will show up in the scoreboard. Currently, there is no efficient way to verify replay handling use, so replays labeled NoRH will not add any scoreboard advantage.
All replays will remain private during the race and will be published once it ends. Races can, while logged in, make their own replays public if they so wish (there is an option in the Scoreboard section for this), but once they do, they cannot revert their replays to private.
For every track, a car will be assigned and all racers must use that car. You are free to use any colour and to select manual or automatic transmission. It is planned to improve this in the future so that racers have some degree of freedom in choosing a car.
If you want to post a replay for a track's permanent competition with rules other than strict OWOOT, the next option is free OWOOT. Sometimes a race may have free OWOOT rules too. All replays that are valid for strict OWOOT, are valid as well for free OWOOT. The difference is that the latter is concerned almost exclusively with being on or over the track and not with executing all stunts. As long as you remain on the main track at all times, it's OK to skip some things.
You can, for example, jump over a cork u/d. Driving over a tunnel is OK too, as well as going through a wall in slaloms (hard, but possible) or skipping loops and corkscrews through the middle. When you are in the air, like after hitting the start of a banked road, it's OK to overfly the grass and then falling directly on top of the bank road at an angle, as long as you don't fall on the grass itself.
Now, if you skip a loop or corkscrew, you have to do it by driving inside them, not around them. You can't drive on grass! While you can partially be on top of a boulevard in highways, you're expected to have at least a part of the car over the pavement. If the whole car is entirely on the boulevard, that's probably too much. On the other hand, flying "over" the boulevard is OK.
This refers to the Gentlement Agreement Rules as defined by Marco. The specific and detailed rules should always be based on the information provided by him. In general, this is more strict than normal strict OWOOT. All GAR-valid replays are OWOOT-valid too, but not the other way around.
GAR always requires that you do not use Replay Handling. If you post a replay as GAR/RH, it is understood that you mean it would be GAR except exclusively for the fact that you have used RH. In other words, GAR/RH is not true GAR.
GAR is strict about shorcuts. There shouldn't be any, ideally. Even things that would be accepted for strict OWOOT, such as speeding up by jumping at the entrance of pipes or in boulevards, cannot happen with GAR. Some speed-ups are tolerated when it's very hard to avoid them and don't affect the results too much, like some slight jump at the beginning of banked roads, but again, this should all be checked with Marco.
This is the most free of all styles, clearly. You are even allowed to go completely off-road, skip anything you want, etc. The important thing is that you start and get to the finish line somehow. In the process, you can get as creative as you want. However, penalty time cannot be ignored. This is the form of driven chosen by ZakStunts.
ZakStunts, the first tournament to use this style, allows for penalty time, but it must be counted, that is, added up to your total lap time. In Race For Kicks, your replay must be penalty-time-free. Changing this to the form of ZakStunts could be considered if important replays containing penalty times were to be posted in the general competition, but so far, penalty time is not allowed.
