The problem
In Teamfight Tactics every reroll costs gold, and the in-game shop odds don’t tell you the one thing you actually want to know: if I roll down now, what are my chances of hitting my 3-star?
What I built
A calculator that takes your level, the unit you are looking for, how many copies are already out of the pool, and your gold, and returns the probability of finding the copies you need.

What I learned
[One or two honest lessons, for example about probability, UI, or testing it during real games.]
