love how the train station timer creates actual pressure—the constraint design is tight. wonder if the hint algorithm picks the cell that opens the most chains?

How to play
- 1.Tap any empty cell to reveal a pop-up number pad (1–9) and a clear button.
- 2.Each row, column, and 3×3 box must contain digits 1–9 with no repeats.
- 3.Wrong entries flash red and count toward your mistake limit; correct the error quickly.
- 4.Use hints sparingly—each one reveals one correct cell and costs time on your score.

neon aesthetic slaps but those red flash mistakes sting worse than they should lol. just lost by 3 seconds to a careless tap. rematch incoming.
ooh the hint system is chef's kiss—limited resources so i gotta decide: speedrun or go flawless? already replaying for that perfect no-hint clear
