Flash Flash Revolution/Terminology

Being a rhythm game, much of the terminology comes from music theory (i.e. note duration).

Arrow/Note Related

Quarters/4ths, Eights/8ths, Sixteenths/16ths, Thirty seconds/32nds, Forty eights/48ths, Sixty fourths/64ths

These are in reference to the type of arrow/note speed. They also represent the general colors of the arrows in the charts of the newer levels (for example: red arrows generally represent 4th notes, while blue arrows represent 8th notes).

Jacks/Minijacks

Jacks refer to quickly repeated arrows, such as four right 32nd arrows in a row. A minijack, as defined by Shashakiro, is "two or three specifically, anything higher is a jack, although "jack" can be used to describe minijacks too." In FFR, jacks are defined by their distance apart in frames, such as multiple arrows 4 frames apart, would be considered 4-frame jacks and so on. Mainly, the jacks that will be seen in the game don't come closer than three or two frames apart, except in a very small handful of songs such as Croudpleaser and Vertex Beta vROFL where 1 frame, and 0 frame jacks can come into play.

Jumps/Doubles/Hands/Quads

Jumps and doubles describe two arrows played at the same time. If there are three arrows to be pressed at the same time, these are hands, or hits that would normally require the use of hands (along with the feet for Dance Dance Revolution). If there are four arrows that are to be hit at the same time, it is considered to be a quad, or quads depending on how many there are in a row.

Streams/Jumpstreams

A stream, is a consecutive series of single arrows (usually approximately the same frame distance from one another) in which a pattern of some sort is formed. This pattern usually has the arrows alternate and usually doesn't contain any form of "jacking" within the stream of arrows. A jumpstream generally has the same concept, but tends to use consistent "doubles" along with as single arrows when forming it's pattern. Jumpstreams can also contain "hands" or "quads" within it's pattern, in this case the term jumpstream is still considered the appropriate term, instead of "handstreams" or "quadstreams".

Rolls

A roll is 4 arrows placed a certain amount of frames apart, in the order of "Left","Down","Up","Right" or "Right", "Up", "Down", "Left". A "roll" can be just a single "roll" over the keyboard, or 1000. Rolls are considered only as "rolls", regardless of their frame distance apart.

Trills

A trill is a series of arrows (presumably 4 or more) that constantly use two arrow keys. Trills can range from very slow, to ridiculous 1 framers as seen in Croudpleaser, and can last any amount of time. Trills are commonly used for two consecutive drum sounds, piano or other speedcore break-beats that repeat two sounds over again for a certain period of time.

Chains

A chain is usually a series of single arrows that changes over to another series of single arrows by using a double note to make it appear like the arrows are linked together (like a chain). They are found in a decent amount of songs, and can be very fun to play with as chains do not usually ever seem to ascend to 4 or 3 frame speeds in FFR.

Combo/Max combo/Full combo

The combo is the current or final number of notes pressed in a row. The maximum arrows you hit in a row within a song would be considered your max combo, which is tallied in to your FFR total by adding 1,000 points for each arrow hit within your max combo. For example, a 450 combo would yield you 450,000 points in addition to your main score. Hitting all of the arrows within a song without missing is considered a full combo, or an FC.

Note Scores

Perfect

Matches the timing nearly exactly.

Good

More off than a perfect.

Average

Not so on time, about 50% accuracy.

Boo

Tapped the key when an arrow was not present, or tapping it below the accuracy for "Average".

Miss

An arrow that went by without being hit; breaks the current combo.

Final Scores

The following ratings don't actually apply to FFR (since they do not appear in the game) - however since most of the community is familiar with other DDR and PIU emulators, other players may reference the quality of their plays and others with these.

• AAA: full combo with all perfects.
• AA: letter representation of a score between 94% and 99.99%.
• A: between 80% and 93.99%.
• B: between 70% and 79.99%.
• C: between 60% and 69.99%.
• D: between 50% and 59.99%.
• E/F: lower than a 50% or failed the song.

Scoring Related

Full Combo (abbr. FC)

Full Comboing is where you don't miss any arrows. By combining a full combo with perfect accuracy on every arrow (by getting all perfects, no goods, averages, boos or misses), you will receive a perfect score, or an AAA.

PA/Perfect Attack/Perfect Accuracy

A scoring method based off of the ratio of Perfects to other stats in your final score (goods, averages, etc). The higher the ratio of perfects to other stats, the better PA you have. A higher PA means you did better on the song; the better the PA, the better the rank. Although a good PA is only truly realized when a full combo on the song is also achieved, as FFR is a high combo based game. Weigh your PA with your combo options on harder songs if necessary, to ascertain the lowest rank you possibly can.

SDG (Single Digit Good)

This is when you play through any song, and end up with a final total of 9 or less goods for your overall stats. A song does not need to be full comboed or have an absence of averages or boos in order to obtain an SDG, but is most credible when a 9-0-0-0 or less is obtained. Being able to obtain a clean SDG on harder songs will give you much lower rankings, and is one step closer to an AAA

Clean/Clean run

Playing through a song clean is when you play any song, and when you end up with a final total of zero boos and misses for your overall stats. Playing a song clean usually means that at no part of the song, were any negative points obtained by doing something incorrectly (such as obtaining a boo or a miss). So a 20-2-0-0 could be considered a clean run, while a 8-2-0-4 could not, as they obtained negative points 4 times during their game play (the 4 boos).

Flags

Black Flag

A AAA on a song except for 1 good.

Ave Flag

A AAA on a song except for 1 average.

Miss Flag

A AAA on a song except for 1 miss.

Boo Flag

A AAA on a song except for 1 boo. Results in the best AA you can receive.
