Practice mode learns what you get stuck on — broken down by operation (+ − × ÷) and digit size (1–3 digits) — and builds each session around your weak spots. Sign in so your progress follows you — normal games start counting toward your stats too.
First, a quick diagnostic: four 45-second games, one per operation, each mixing 1-, 2-, and 3-digit problems. It maps your baseline so practice can target what’s actually slow.

Practice adapts to you, so its numbers move as the difficulty does. The benchmark is the one fixed test — the classic 120-second game at standard zetamac settings — making your trendline and personal best comparable over time.

Session recap
Multiplayer
Create a room for two to eight and share the code, or join a friend’s. Everyone gets the same problems in the same order; the format decides whether you race for each one or run the set at your own pace. Once everyone in the lobby is ready the game counts in, and after the buzzer the room comes back to its lobby for the next one — join mid-game and you’ll watch until a seat opens. Anyone with the code can watch live.
