Ponderanda · Day 1
Day 1 was set on 16 August 2026. Five arithmetic problems, the same five for everyone on the planet, and one attempt each.
A wrong answer ends the day, and that is fine — the thing being recorded is that you turned up, not that you were perfect. There is no timer on the screen, missing a day costs nothing, and every past day stays playable for free.
Coming to Android. Ponderanda is free, and there are no ads at all while you are solving the daily ladder — that part is permanent.
It will not make you smarter, and does not pretend to. It will make you faster at arithmetic. Read the rest.
