The popular TV show揇eal or no Deal?is sweeping the world and is now available on television screens all around the world. Chances though are slim that you will make it on the show as one of the contestants, but I抦 happy to report that you can play 揇eal or no Deal?anytime on the internet.
The show is now produced in almost 60 countries, with almost another 20 similar versions, across six continents. And it抯 the most flexible game show ever. It can be played in hour- or 90-minute long primetime slots, or work as shorter, daily shows. In some countries, the glitz, models, 26 suitcases and questions are replaced by regular contestants, with 22 boxes. Sometimes the banker is shown in silhouette, or he抯 a mysterious voice at the end of a phone. Sometimes it抯 the host that offers deals. The winning contestant can be helped by family and friends in some countries, or he could be out on his own. But wherever, and whatever way, you watch Deal or No Deal, the tension, the excitement; the drama and surprises are always the same.
In DOND you start by choosing the box to keep that you hope contains the big prize then carefully select which of the remaining boxes to open, revealing their contents. Rest assured The Banker will attempt to do you a good deal and buy your box with a shrewd offer. Now the choice is yours to deal or no deal in the hunt for the big prize.
The mathematicians out there will already have noticed that the expected value for Deal or No Deal is simply the arithmetic mean, or more simply, the average dollar amount remaining in the cases. Let抯 say you have four boxes left which contain ?000, ?00, ?00 and ?00 which make the sun of ?800. The mean would be ?800 divided by 4 which equates to ?50. If you are offered more than ?50 then you should deal. Risk aside, accepting a 揹eal?for less than the mean should generally be regarded as a poor decision as this is below your expected return.
The online game works in exactly the same way but you need to factor in your initial stake to make your decision. As a rule you should set a stop loss of 75% of your initial stake compared to the mean of the remaining boxes.
If you intend to play 揇eal or no Deal?for real money then it would be very wise to play the free version of the game to gain a complete understanding and finalise your strategy before risking your own hard earned cash. Also many online sites will offer new sign ups a bonus which in many cases will double your initial stake and so give you an even greater chance of a win if you use a good strategy.
So in simple terms resist the urge to gamble and don抰 accept bankers offers less than the mean of the remaining boxes and you will not go far wrong!
