The idea is to create a a general path of how you can walk to an arbitrary place. The discrete units that are incremented or decremented would be one step along two-dimensions. This means you can move, at each increment, one step forward, one step backward, one step to the left, or one step to the right. What determines which direction you move in is the the outcome of a roll. It would be as follows:

Roll a 1=Take one step forward
Roll a 2=Take one step backward
Roll a 3=Take one step to the right
Roll a 4=Take one step to the left
Any other number= Don’t take a step and roll again (subtract that from the alloted quota of steps)

To make this precise, you will have to define the distance of what constitutes a step. That is up to you. However you decide to define it, keep in mind that the distance has to be consistent for each step, so if the first step is x number of units, then the next step would have to be the same number of units. Also, with enough time and in two dimensions, it is quite possible to randomly get to your destination by walking everywhere in the space you are dealing with, so you would also need to set a finite number of steps.

The goal of the exercise is to get from a starting point to a specified ending point via using psychokinesis to influence the random walk. The dice is rolled and whatever number it lands on determines what step to take. Wait! This isn’t truly random! That doesn’t matter. Yes, while it is true that technically rolling a die is deterministic, it is highly unlikely for a human to roll the die the same time every time without deliberate application of a technique; therefore, a random attribute is introduced which creates chaos causing the rolls of the dice to practically be random. Subtle variations in how the die is rolled every time due to the fact human physiology is stochastic will introduce chaos into the rolls so that it is practically random.

There are different ways to approach this. You can use psychokinesis to constrain all possible dice rolls to lead to a selected path. Instead of doing it roll by roll, you can do one psychokinetic shot and focus on all rolls being constrained to outcomes that correspond to the path. Another approach would be to influence each roll per the path you need to take to get to the destination.

Due to the nature of random walks in two dimensions, there is a possibility that you will make your way to the destination without it being due to psychokinesis especially if given enough steps. That possibility becomes smaller and smaller and smaller the more consistently you can do this along with a shorter and shorter constraint on the number of steps. So, if you can make your way to whatever destination you set within a particular a constraint, try it again.
