Same challenge for everyone
The daily challenge is shared, so the leaderboard compares players solving the same sequence, not random exercises.
Mental math game
Mental math game with daily rankings
Numday turns mental arithmetic into a quick daily game: solve 7 accumulated calculations, beat the 90-second clock, and compare your score only after you finish.

A mental math game built around one clean loop
Many math games become endless drills. Numday is narrower: one current challenge, one scored start, a visible result, and an optional ranking step. The goal is to make mental math feel like a daily ritual rather than homework.
The core mechanic is accumulated calculation. If the game shows 7 x 8 and you answer 56, the next prompt can use that answer as the starting value, such as 56 + 24.
Mental math practice without losing the daily attempt
Practice mode is separate from the competitive daily challenge. It lets you learn the accumulated-chain mechanic with a new non-competitive sequence and does not consume the scored daily start.
