Mode-by-Mode Strategy
Marathon, Sprint, and Ultra each call for a different strategy.
Marathon is about surviving as long as possible while racking up points. Keep the stack low even as speed increases, and cash in points with Tetrises and T-spins whenever you have breathing room.
Sprint is a time attack to clear 40 lines as fast as possible. Rather than flashy techniques, what matters is filling quickly without gaps and shaving time with hard drops and finesse.
Ultra is about maximizing your score within 2 minutes. The key is building a stable setup early, then pouring on the points with Tetrises, T-spins, and combos in the time you have left.
