Summarize this article in one sentence.
These should be in the game itself upon purchase, and you will need all of them to play it right.  Winks are small plastic discs that you try to get into the pot. The squidger is a larger piece of round, thicker plastic that you use to propel smaller discs into the pot. Winks come in yellow, red, green, and blue. There are 6 winks of each color. The pot is the container that you try to put the winks into. The mat is basically the playing field. It’s usually 6 feet by 3 feet. Place the mat on a flat surface in order to play. The mat has lines etched on both ends. This indicates the field’s boundaries and baselines. The mat is usually made of felt. The goal of Tiddlywinks is to propel as many winks into the pot as you can.  You can either play Tiddlywinks in two-person teams or against another player. It’s also possible to play the game with three people. Only 2 to 4 people can play Tiddlywinks. The verb “to squidge” means you propel or flick the smaller plastic discs toward (and hopefully into) the pot using the squidger. The way you squidge a wink is by putting your squidger on a wink. Apply pressure to it, and it should pop the wink forward. It can be difficult to squidge a wink when someone else’s wink is on it. The wink below another wink is said to be “squopped.” You must only touch the top wink in your color sequence. If all the winks are squopped, the game is over. Some people sandpaper their squidger down. This will make it so they have less sharp edges.  Some people use different size squidgers for different shots.  Squidgers must be round and between 25 mm and 51 mm across and no thicker than 5 mm. They cannot damage the winks. You may only use one per play. However, you can use different squidgers throughout the course of a game.

Summary:
Make sure you have all of the pieces you need to play Tiddlywinks. Understand the game’s object. Use the right squidger.
