The Wii remote is used to play games on the Wii and about six months ago my husband bought a Wii and two games from the bootsale for £50 which I thought was a good price to pay.
The Wii remote came with it but you can buy them for around £20 and upwards from The game shops in towns or from online and the price varies depending on where you buy it from.

The Wii remote is white and oblong and as we had never used the Wii before it takes a little time to get to know the gadget and controls so you have to practice. It has motion sensors in it which once aimed at the television you can interact with the game. I was quite amazed at how sensative these actually are.
If you haven't used the Wii remote before you have to attach the sensor bar to the console and this sits on top of the television, the Wii remote can then be used within a certain range of the sensor.

The Wii remote has the same controls as an ordinary game controller if you turn it on it's side it has the four buttons for up down right and left controls which also do the jump and run motions these controls are used for the games like mario and other Wii games, but I like to play golf on mine and then you can use the Wii remote by holding it in your hand like a golf club and swinging it to get the feel of the game.
It has a strap you can put on your wrist so you don't let go of the remote whilst playing a game as accidents have been known to happen when the remote has been swung and let go of whilst in play.

To use the Wii remote to play baseball, golf, bowling and other interactive games you have to hold it in your hand and use the button at the back of the remote to hold swing and let go, so that your alter ego on screen can do the motion it's supposed to i.e throw a bowling ball, or swing a baseball bat.

The Wii remote takes two AA batteries, is connected by bluetooth and has a blue light meter on the remote to let you know when your batteries need charging again.
You can also get a Wii remote jacket which the remote sits in for better grip. I have one but still use it as it is, without the jacket on.

You press the home button to access the menu on screen and then you can choose what you want to do and which game to play or look at the Mii section, as well as internet access, news channel, weather forcast and other features.
I haven't really used it to it's full potential yet as I just play the Wii sports games to keep fit and have fun.

All in all I find this a good remote controller, it is great to use if you haven't played the games before as it has a rumble motion to give the game an extra feel to it, I like the interactiveness of it as you feel like your part of the game more than just sitting at a screen pressing buttons, you have to be on your feet more so it's fun.

I think this is one of the best gadgets invented for game players.
