Play Sudoku Classic Online

Sudoku Classic uses traditional Sudoku rules and gameplay while adding a new design to keep it fresh. There are multiple difficulties you can play, which makes the game very suitable for players of any skill level to attempt to beat the puzzles – there is an Easy mode for beginners and a Very Hard mode for experts.

The game also features a timer that shows you how long you’ve played and helpful features that can assist you while you play.

You can progress gradually

What’s unique about Sudoku Classic is that even if you’re a new player, you can progress through the difficulty levels while playing. You can start at Easy and get a grasp of how the game is played, and as you get better, you can play harder and harder game modes.

Your high score is determined by how quickly you manage to complete a level. You start with a specific amount of points, with the amount being different depending on which difficulty mode you’ve chosen. Every 3 seconds, you lose 10 points off your score. Tracking the timer and playing with haste is not only suggested but necessary if you want to set an impressive high score.

The game also has some mechanics that you can use to your advantage if you’re struggling. For starters, if you try to put a digit somewhere on the board, and the same number is present in its row, column, or square, the game won’t let you place it there. Additionally, every 30 seconds, you will receive one Hint that you can use. Once you use it, it will enter a number for you, saving you some time. A good tip is to use the hints as soon as they’re available, as you’re not punished for using them.
