The truth is that all the probability calculations we make in Teamfight Tactics are only relative. For instance, at level 7, we have a 40% chance of getting a 3-cost champion, but many times we have to roll nearly 20 gold just to find the champion we need, while sometimes the game just gives it to us without needing to roll. This isn’t purely a matter of luck; it’s simply that we don’t have the right tools to calculate accurately.
Recently, a gamer shared the results of his 4-month diligent research on the Teamfight Tactics subreddit—a calculation and training tool that closely aligns with reality. This gamer, named Edzwoo, has designed a website called Donkeyroll.gg, which includes incredibly useful features that allow players to calculate champion appearance rates with extreme accuracy.
Another skill you can practice on this platform is the ability to find the units you need when rolling at high speed. Many people miss out on some units they need when they have to roll quickly because time is running out, their health is too low, and they’re about to “die.” You can select a few units and roll at high speed to calculate how many units you might have missed.
One limitation of Teamfight Tactics is the lack of a training mode. If you want to experiment with building a new team composition or understand the actual appearance rates of champions, or simply enjoy “rolling for fun,” you can only do this by playing the game directly. If you want to practice and test your true “luck,” give Donkeyroll.gg a try.
