Nebula Sudoku: Solve the Grid, Boost Your Mining Rate
# Nebula Sudoku: Solve the Grid, Boost Your Mining Rate
Nebula Sudoku is part of the Nebula Games & Utilities tab inside the app and on the website. It is a full Sudoku engine with four difficulty tiers, built to run entirely in your browser or phone — no extra download, no account beyond the one you already have.
How it works
1. Open Games & Utilities and pick Nebula Sudoku. 2. Choose a clearance level. Higher tiers start with fewer given numbers. 3. Fill the grid so every row, column and 3x3 box holds the digits 1 to 9 exactly once. 4. Finish the board and your score is submitted automatically.
Your score depends on the difficulty you picked, how quickly you solved it, and how few mistakes and hints you needed. A careful, fast solve on a higher tier scores far above a slow one on the easiest level.
The mining boost
Reaching a score threshold awards a mining boost that applies to your mining session for the rest of the day. Boosts from different games stack: earning +5% in Sudoku and +5% in another game gives you +10%, up to a daily cap of +15%.
The boost is applied server-side, so it shows up in your Rate Composition panel on the mining screen. If you start a new session later the same day, the boost you already earned is applied to it automatically.
Each game can be played once per day for a boost. You can keep playing for fun after that — the score just will not add another boost.
Why we built it
Nebula is a cloud earning app, not an arcade. The games exist because we wanted a way to reward attention and consistency that is not another advert. A few minutes of a real puzzle is a better trade for your time than a 30-second video, and the reward lands in the same place: your effective earning rate.
Tips for a higher score
- Scan for cells with only one possible digit before guessing anything.
- Work box by box on lower tiers, line by line on higher ones.
- Avoid hints — a hint-free solve scores noticeably better.
- Do not rush the first pass; a wrong digit costs more time than it saves.
Where to find it
