When a Calculus is played it can be Haddocked or Flipsies'd by the Snowy.
Any combo card played on a calculus must be the same colour as the calculus. Multiple Haddocks (A Haddock Supper or a Special Fish) may be played as long as the leading Haddock is colour matched to the top Calculus. This changes the colour of the stack to the trailing Haddock's colour.
Only one Flipsies may be played on a Calculus.
A Haddocked Calculus skips a number of players equal to the number of Haddocks played starting with the Snowy.
A Flipsies'd Calculus bounces back to the Calculator.
Tintins can be combo'd in the same way but by any colour of combo card. Once a combo card has been played on a tintin usual colour rules must be followed.
A combo can itself be combo'd and can also be stacked with more Calculuses or Tintins depending on which the combo starter was.
