To achieve the highest scores in the Marathon mode of Tetris Effect, it is vital to adopt effective strategies that leverage the game’s unique scoring mechanics. Here’s a detailed outline of the strategies you should focus on:

1. Start at a High Speed Level
– Choose Speed Level 13: Starting at a higher speed level significantly enhances your score potential. Line clears at higher speeds yield more points. Many top players recommend beginning at speed level 13 for its ideal balance of challenge and scoring potential.

2. Focus on Advanced Line Clears
– Perform Tetrises and T-Spins: Advanced clears, especially Tetrises (clearing 4 lines at once), and T-Spins (clearing lines with a T-shaped piece), are key to multiplying your score.
– Tetrises: Each Tetris scores 800 multiplied by your current level. Thus, at level 13, this results in 10,400 points per Tetris.
– T-Spins: T-Spin doubles can yield 1,600 points times your level, while T-Spin triples can achieve even higher scores, making them incredibly valuable for high scoring.

3. Maintain Back-to-Back Chains
– Create Consecutive Difficult Clears: Aim for back-to-back Tetrises and T-Spins without any regular line clears in between. This strategy activates a 1.5× multiplier for each subsequent difficult line clear within the chain, greatly amplifying your total score.

4. Build Combos
– Continuous Clearing: Focus on executing line clears with every dropped piece to create combos. The points from combos scale with your current level, providing additional score increments as you progress.

5. Strong Opening Strategy
– Utilize Openers like Perfect Clears or T-Spins: Starting strong with setups like a Perfect Clear or an initial T-Spin can give you an early scoring advantage. This early boost is compounded with subsequent clears, setting a solid foundation for the rest of the game.

6. Understand the Game’s Mechanics
– 150 Lines and Speed Increments: In Marathon mode, your objective is to clear 150 lines while speed levels increase progressively. By starting at a higher speed, you maximize potential scoring opportunities right from the beginning.

Conclusion
In essence, to maximize your score multipliers in Tetris Effect’s Marathon mode:

– Start at a high speed level, ideally around 13.
– Focus on clearing Tetrises and T-Spins for maximum point multiplication.
– Achieve back-to-back line clears to trigger score multipliers.
– Maintain a flow of combos to continually build your score.
– Employ an effective opener to ensure a strong start and a good cumulative score.

By employing these strategies, you can effectively harness Tetris Effect’s scoring mechanics, driving your achievements in Marathon mode to new heights. Happy stacking!
