HOW TO PLAY

sudoku grand · two modes

The Basics

Fill the 9×9 grid so every row, every column, and every 3×3 box contains the numbers 1 through 9 — with no repeats.
Tap a cell to select it, then tap a number at the bottom to place it. Grey numbers are given — you cannot change them.
Notes mode — tap the pencil to toggle. In notes mode, tapping a number adds a small pencil mark to help you track possibilities.

◇ Advanced — The Solitary Descent

◆◆◆
You start with 3 lives. Every wrong number costs one life. Lose all three and the grid is lost.
Complete a full row, column, or box and that section ignites — the yantra behind the board comes alive, piece by piece.
🔥
Chain correct placements for combos — the longer your streak, the higher your score per move.
Use Hints (3 per game) when stuck. Use Erase to clear a cell you placed.
Win condition: Fill every cell correctly. The yantra blazes to full radiance when the grid is complete.

◆ Elite — Duel The Ancient

You and The Ancient — a mysterious rival — solve the same puzzle at the same time. First to finish wins.
👁
Watch the rival's mini-board at the top. Its progress bar fills in real time. When it gets close, the screen pulses red and a heartbeat begins.
Place numbers 1–5 correctly to earn combat powers. Numbers 6–9 are plain — no power.
💰
Earn coins by finishing duels. Win = +25 coins, lose = +8 coins. Spend coins to buy power charges mid-duel.
Win condition: Complete your grid before The Ancient completes theirs. At the last second — silence, then eruption.

💡 Tips

1
In Elite, save your Swap and Steal — they're once per game. Use them when the rival is close to winning.
2
In Advanced, use Notes to pencil in possibilities before committing — it saves lives.
3
The yantra lights up as you solve. Complete rows and boxes to see more of it awaken.
4
The rival rubber-bands — it speeds up when you're ahead and slows when it's ahead. It's always close. Don't relax.
