Dear Game Maker,

I really appreciate that you have contacted me. In this case it seems that the design of

your game needs some adjustments. As you noticed, after trying the game with the help

of volunteers, players are losing points after few turns. This can be explained using

probability theory. The concept that we will use in this case is called expected value, which

is the long-run average value of repetitions of the experiment it represents.

First of all we assume that each section is equally likely to appear, and no biases affect our

trials. This means that the probability for each event is equal and it is equal to1/12. As

each player gives up 10 points with each move, we are going to calculate the expected

“profit” for each move. In example if a player is lucky enough to get the 40 points section,

the profit in points will be 30 points, for the sections with 10 points it will be zero points

and for the “Try again” sections it will be -10 points.

Considering these facts we can calculate the expected value, which is the sum of each

variable’s multiplication with the corresponding probability. Expected value is symbolizes

as E(X), and in this case it is equal to E(X)=30×1/12+4×0×1/12+7×(-10)×1/12=-3.33

As we can see the expected value is negative, so it’s expected that players are losing points

in the long run. Considering that, you have to make some adjustments in your game

design.

As you mentioned you want the players to win at least one point in the long run, so the

expected value has to be at least 1. As you...
