Frequently asked questions
Q: Is there a penalty for a wrong move?
A: Yes. Incorrect taps will add a "Time Penalty" to your score or reduce your "Life Hearts," forcing you to be precise rather than using trial-and-error.
Q: Can I unlock larger grids?
A: Yes. Completing the "Beginner" 5x5 grids unlocks the "Master" 15x15 and 20x20 matrices, which feature multiple layers of overlapping logic rules.
