1. Add Classical 9x9 mode

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.

This update focuses on polishing the core game feel and making every puzzle fair, responsive, and accessible. - ** - **Smoother visuals - Better feedback: Added haptics - Pause anytime: Tap the - **Mist - **More Thanks for playing — more levels and features are on the way!
