Under the surface it is a test of pattern recognition and pattern recognition, dressed up in tense presentation.

How to play Modern Sudoku

Tips and tricks

Watch the edges of the screen, not just your character. New threats almost always enter from the sides or the top, and spotting them early gives you a full second of extra time.
When you die, note exactly what killed you. The answer is usually one specific pattern, and fixing that one thing is worth more than "trying harder".
If there is a dash, jump or dodge move, treat it as a resource: use it to escape, not to attack, until you know the level.
Keep moving. Standing still is the most common way to lose an action round, because the game is designed to punish hesitation.
