Oh, for a larger grid, you might want to have letters anyway, because your point still applies.

It's interesting that log_2 2028 is just above what you can represent in a single digit. That's very close to merging two 9s.

I'd like to actually see someone pit x, log_2 x, and letter(log_2 x) against each other in an A/B test of the game. The latter two are simpler, but the former might be more exciting, because of bigger numbers.
