The workshop is meant for beginners at 4-handed Siteswaps or Zaps (or both). The six patterns of the workshop use 4-6 clubs and also contain single passes, zips and a few Flips (4).
In passing, hijacking is where one passer decides to change what pattern they are passing and their actions transitions their partner into a compatible pattern. Collectively these are also known as “programming” because you are programming your partner. Most people use programming and hijacking interchangeably.
