Every sequence has a difficulty on the same scale as your rating. Your rating goes up when you answer faster than expected for that difficulty, and goes down when you answer more slowly or skip.
The next sequence is picked near your current rating. A new player starts at 800. Sequences start with a fixed step, such as 5, 9, 13, 17, and move on to powers, growing steps and two rules at once.
Listen Mode
In Listen mode each sequence is read aloud and not shown. Listen mode has its own rating. Press R or Repeat to hear a sequence again.
