Number Series — the complete help guide
Number Series is a collection of number puzzles and brain games for Android. This guide explains how to get around the app and how to play each game — one topic per page, in plain words, using the same names you see on screen.
Number Series has a lot of games in it, and they are deliberately different from each other: some are calm and untimed, some race the clock, some are one puzzle a day and some never end. This guide walks through all of them.

Frequently asked questions
- Where do I start if I have never played?
- Open the Play tab and tap Challenges for today's Daily Challenge, or New game for Classic. Your very first puzzle walks you through how it works, and every mode shows a short tutorial the first time you open it.
- Do I need an account?
- No. You can play every mode without signing in. Signing in with Google adds cloud backup of your progress and the Friends features.
- Can I see a mode's rules again later?
- Yes. Every game screen has an info button in the top right corner that opens the rules, and Settings → Game → Reset Game Tutorials brings back all the first-time tutorials.
