🎮 CryptoSudoku – Game Rules

How to play CryptoSudoku?

The puzzle is played on a 9×9 grid, divided into nine 3×3 blocks.

Instead of numbers, the grid uses cryptocurrency symbols:
₿, Ξ, 🪙, 💎, 🐕, 🌐, 🚀, 💰, 🔗.

The goal is to fill the empty cells so that:

• Each row contains all 9 different symbols exactly once.

• Each column contains all 9 different symbols exactly once.

• Each 3×3 block contains all 9 different symbols exactly once.

You can change the difficulty level – the higher the level, the fewer starting symbols are given.

Use logic and reasoning to solve the puzzle. No guessing is required!

The timer tracks your solving time – try to beat your personal best.

✅ When the grid is correctly filled, you win the game!
