NumberBox9

The classic campaign mode is here. Journey from 3x3 beginner all the way to 9x9 grandmaster across 7 stages and 115 levels, with difficulty ramping up within each stage. Only the first level is open by default; clear a level to unlock the next, and clear the last level of a stage to unlock the next stage. - Campaign: 7 stages (Beginner, Advanced, Challenge, Skilled, Expert, Master, Grandmaster). Difficulty steps from Easy to Master within each stage. - Timer: The clock starts on your first move. Pause anytime, and the app auto-pauses when sent to the background. The header shows your live time in MM:SS format. - Records: Each completion saves your best time and star rating. The result screen shows your time, personal best, and target time, with a New! badge when you set a record. - Star ratings: 1 star for finishing, 2 stars for beating the target time, 3 stars for finishing within 80% of the target. Level select shows your stars and best time. - Records Center: Overview of total stars and cleared levels, per-stage progress, and a list of your recent completions. The tutorial and free practice modes are still available from the Select Mode screen. Enjoy the fun of numbers.
