What is Back-to-Back?

Back-to-Back (B2B) is a bonus for performing consecutive difficult clears without any easy clears in between.

Difficult Clears

These clears are considered difficult and maintain your B2B chain:

  • Quads (4-line clears)
  • T-Spin Singles (full, not mini)
  • T-Spin Doubles
  • T-Spin Triples
  • Perfect Clears

Easy Clears (Break B2B)

These clears break your B2B chain:

  • Singles
  • Doubles
  • Triples
  • T-Spin Mini Singles
  • T-Spin Mini Doubles

B2B Bonuses

  • Scoring: 1.5x multiplier on base points
  • Garbage: +1 extra garbage line sent

Example

  1. You clear a Quad (difficult) - normal scoring
  2. You clear a T-Spin Double (difficult) - B2B active! 1,200 x 1.5 = 1,800 base points, 4 + 1 = 5 garbage
  3. You clear another Quad (difficult) - B2B continues! 800 x 1.5 = 1,200 base points, 4 + 1 = 5 garbage
  4. You clear a Double (easy) - B2B breaks. Normal scoring.

Strategy

  • Alternate between Quads and T-Spin Doubles to maintain B2B
  • Hold your T-piece for T-Spin setups while building for Quads with I-pieces
  • In competitive play, maintaining B2B is essential for maximizing damage
