Tiddlywinks

Tiddlywinks is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Tiddlywinks rather than just read about it. In short: Tiddlywinks is a game played on a flat felt mat with sets of small discs called winks, a pot, which is the target, and a collection of squidgers, which are also discs. Players use a squidger (nowadays made of plastic) to shoot a wink into flight by flicking the squidger across the top of a wink and then over its edge, thereby propelling it into the air.

Key takeaways

  • Tiddlywinks belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Tiddlywinks to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Tiddlywinks from memory before moving on to harder problems.

Reference excerpt

Tiddlywinks is a game played on a flat felt mat with sets of small discs called winks, a pot, which is the target, and a collection of squidgers, which are also discs. Players use a squidger (nowadays made of plastic) to shoot a wink into flight by flicking the squidger across the top of a wink and then over its edge, thereby propelling it into the air. The offensive objective of the game is to score points by sending your own winks into the pot. The defensive objective of the game is to prevent your opponents from potting their winks by squopping them: shooting your own winks to land on top of your opponents' winks. As part of strategic gameplay, players often attempt to squop their opponents' winks and develop, maintain and break up large piles of winks. Tiddlywinks is sometimes considered a simple-minded, frivolous children's game, rather than a sophisticated strategic game. However, the modern competitive game of tiddlywinks made a strong comeback at the University of Cambridge in 1955. The modern game uses far more complex rules and a consistent set of high-grade equipment.

Etymology Tiddlywinks derives from British rhyming slang for an unlicensed public house or a small inn only licensed to sell beer and cider (tiddlywink, kiddlywink). Tiddly was slang for an alcoholic drink. It may be related to pillywinks.

Rules

Tiddlywinks is a competitive game involving four colours of winks. Each player controls the winks of a colour, the colours being blue, green, red and yellow. Red and blue are always partners against green and yellow. There are six winks of each colour, which begin the game in the corners of a felt mat measuring 6 feet by 3 feet. This mat is ordinarily placed on a table, and a pot is placed at its centre. There are two primary methods of play with the four colours of winks: a pairs game, and a singles game. The pairs game involves four players, playing in partnerships, with each winker playing a single colour. The singles game involves a single winker playing against another single winker, each playing two colours of winks in alternation. The players take turns, and there are two basic aims: to cover (or squop) opponent winks, and to get one's own winks into the pot. As in pool or snooker, if a player pots a wink of their own colour, they are entitled to an extra shot, and this enables a skilled player to pot all of their winks in one turn. The point of squopping, which is the key element distinguishing the modern competitive game from the child's game (though recognized in even the earliest rules from 1890), is that a wink that is covered (even partially) may not be played by its owner. The wink on top may be played, though, and sophisticated play involves shots manipulating large piles of winks. The game ends in one of two ways: either all the winks of one colour are potted (a pot-out), or play continues up to a specified time limit (usually 25 minutes), after which each colour has a further five turns. Then a scoring system is used to rank the players, based on the numbers of potted and unsquopped winks of each colour.

Strategy The important appeal of the game for many players is the required combination of manual dexterity and strategic thought as well as tactics. Tiddlywinkers often claim that the game combines physical skill (such as in snooker or golf) with the strategy of chess. Tiddlywinks is unique in the combination of skill and strategy it requires. Strategy in tiddlywinks is often rather deep, since winks can be captured by squopping (covering) them. Strategic and tactical planning involves anticipating opponents' moves rather than just building a sequence of one's own moves. Another factor that complicates the game is that there is a time limit to the play of the game; it does not merely run until some objective in the game has been met. All in all, tiddlywinks goes beyond the purely cerebral nature of a game such as chess. The fact that shots can be made or missed, together with the continuum of possible outcomes, makes strategy much less rigid than in chess, and prevents planning more than seven or eight shots in advance.

Equipment The winks and pot used in competitive play are standard, and are supplied by the English Tiddlywinks Association. The pots are made of moulded plastic (historically always red), with specified diameters at the top and the base, and specified height. The winks are made to specified measurements, and are made by slicing an extruded cylinder rather than by moulding, and then smoothing them in a tumbler. Although this leads to some minor variation in thickness, it produces a much smoother edge to the wink than that seen on cheap moulded winks. The mats are made of thick felt. Mats obtained from different suppliers have different characteristics, and part of the skill of a tournament player is to adjust to different mats. Squidgers are custom-made by their owners or purchased from squidger makers. A player may use as many as they like, selecting an appropriate squidger for each shot. Top players may carry up to twenty different squidgers, but will not typically use all of them in one game. The rules governing squidgers permit a range of dimensions, and the material is not specified, except for the condition that squidgers must not damage either the winks or the mat. Modern squidgers are predominantly made from different types of plastic, though antique ones were made from bone, vegetable ivory, and other materials. Squidgers are usually filed or sanded to form a sharp edge and then polished.

Worked examples

Example 1 — a first encounter with Tiddlywinks

Start with the simplest possible case. Write down what Tiddlywinks claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tiddlywinks before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tiddlywinks ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tiddlywinks

In research
Tiddlywinks appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Tiddlywinks in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Tiddlywinks is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1888 introductions, Children's games, Disk-flicking games, so understanding it makes those chapters shorter.
In everyday life
Look for Tiddlywinks outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
