Back-to-Back (B2B)

Difficulty: Intermediate

Chain Tetrises and T-spins consecutively to earn a score multiplier.

Back-to-back is a bonus earned by landing consecutive 'difficult clears' — such as a Tetris (4-line clear) or a T-spin — with no ordinary clear in between. When it applies, a score multiplier kicks in.

A plain clear, like a single or double, in between breaks the back-to-back chain. So aim to finish clears with a Tetris or T-spin whenever possible to keep the chain alive.

Alternating Tetrises and T-spins to extend a back-to-back chain as long as possible is central to advanced high-score play.
