To do this you basically play a pot shot as though the pile was the pot. Each round ends with the colour who won the squidge off. So if blue is playing as time runs out, and red won the squidge off, red's next go is said to end round zero. After this everyone gets five more turns, ending with the squidge off winner. If all six winks of one colour are potted, that colour is said to have potted out.
Players continue to play in normal order, and just try to pot their winks.
Any squops which occur are desquopped. Tiddlies aren't counted. The first colour to pot all six gets 4 points, second gets 2 points and third 1. The tactics of tiddlywinks can seem bewildering at first. To counter this, ex-World Champion, Dave Lockwood, set down some general guidelines.
