SudoG — Sudoku against the clock

Three, two, one — and every second counts. SudoG turns Sudoku into a race: speed earns points, chains of correct moves earn more, wrong attempts cost. At the end there is a number, and it can be beaten.

Thinking time — then the beat drops

Before the round starts, a countdown runs and the grid is still blurred. Use those seconds: anyone who already has the easy cells in mind starts with a head start.

After that every second counts towards the score. The bar at the top shows the heat: set quickly and correctly and it stays high, collecting bonuses. Hesitate and it slowly drops again.

Points for speed
Chain bonuses for streaks
Medals at the finish
High scores per level

The animation on the right is the in-app tutorial itself — that is exactly how a round begins.

Six levels for the race

Starter, Very easy, Easy, Medium, Medium+ and Hard. Deliberately no technique levels: against the clock it is about speed and overview, not about X-Wings. If you want to hunt patterns, SudoP is the place — all ten levels are there.

Help 1 highlights solvable cells (−20 % base points), Help 2 shows possible digits (−50 %). Both optional.

SudoG: choosing difficulty, helps and stealth mode

Stealth mode — for those who have it

No helps, full time pressure, and a hundred times the possible points in return. The mode for people who carry their Sudoku in their head and want to know how far it takes them.
