I echo what the others say about the current interface. I think there is an opportunity for "normal" and "hard mode" like Wordle. In normal you are given the names of the factors but have to enter the expressions for their value (no default values given). In hard you have to come up with your own factor names as well as the values (the name is purely aesthetic for the user to keep track of their ideas). The win condition is the same (be within an order of magnitude of the answer) but maybe there is a special "super" win for being within 10% (log scaled, so lower bound n^0.9 and upper bound n^1.1).
