This post assumes you have an understanding of how to play Can’t Stop. You can read a copy of the rules on BoardGameGeek.

After playing a few dozen games of Can’t Stop on BoardGameArena, I decided to build a calculator to see if my intuitive feeling of the percentages matched up with reality.

Calculating Bust Probability #

The first step is to identify what we are looking for. When playing Can’t Stop, the most useful information is the bust probability. Bust probability is a function of two variables: completed tracks, and in-progress tracks. Completed tracks is a list of all tracks that have reached the top. In-progress tracks is a list of all tracks that the current player is currently climbing. From these, a list of valid sums can be calculated: if there are fewer than three in-progress tracks, this is a list of all non-completed sums. If there are three in-progress tracks, then it is the in-progress sums minus any “tentatively complete” sums.

Next, I need to calculate all possible combinations of the dice. In total, there are 1,296 different rolls for four dice — 6^4. For each of these, there is between one and six possible sums to choose from. Lastly, I need to divide the possible combinations with a valid sum by all possible combinations. This is your chance of busting!
