The genre lives on a calm pace, levels that teach one idea at a time and clear rules that never change unfairly. Sudoku understands that, and it shows in the first minute of play. Playing it works your planning and planning, which is a large part of why the "one more round" feeling is so strong.
How to play Sudoku
- Start by clicking the big play button. Sudoku loads inside the frame; give it a moment, especially on a slow connection.
- Follow the on-screen prompts. The developer describes the controls like this: Pick the difficulty level your prefer you can choose from the easiest one Easy mode so you can train your brain and solve the puzzles with a simple level of logic and memory but you can also choose the Hard Very Hard…
- Read the whole level before your first move. Identify the goal, then look for the forced moves that must happen regardless.
- Switch to full screen if precision matters, and remember that the game keeps its own progress — finish a level before you close the tab.

Tips and tricks
- Work backwards from the goal. Ask what the final state has to look like, then ask what the state before that must be.
- Look for forced moves — places where only one option is legal. Solving those first shrinks the problem.
- Use undo or restart freely. Experimenting is how you learn the mechanics; there is no penalty for trying an idea.
- If you are stuck for more than a couple of minutes, step away and come back. Puzzle solutions often arrive when you stop forcing them.

In terms of time, think of a level or two in five minutes, or a long relaxed session. The learning curve is gentle at the start and genuinely tricky later. The controls are tap and drag based, which makes it comfortable on touch screens as well as with a mouse.
