What is a combo in Tetris?

A combo rewards you for clearing a line every single time you place a piece. Keep the streak alive and the bonuses snowball, especially against a human opponent.

The short answer: A combo is a streak of line clears made by consecutive pieces, with no piece placed in between that fails to clear a line. Each clear in the streak raises a combo counter, and the higher it climbs the more bonus points and attack it produces. Break the chain by placing a piece that clears nothing, and the counter resets to zero.

Chaining line clears

The combo counter ticks up whenever a piece clears at least one line and the piece before it did too. It only cares that each piece keeps the chain going, not how many lines each clears. That means a long ladder of single clears can build a surprisingly large combo if you set your stack up to feed it.

How combos score

Every step of a combo adds points on top of the clear itself, scaling with the length of the streak and your level. The exact bonus follows the same guideline math as the rest of your Tetris score. Longer combos are worth chasing precisely because the reward grows the longer you sustain them.

Combo strategy and openers

In head-to-head play a combo becomes a weapon, since each link sends extra garbage across to your rival. Some players open with dedicated combo setups that guarantee a long streak of clears. Try it live against a friend in the multiplayer lobby, where a big combo can bury an opponent fast.

How does scoring work in Tetris?

Guideline Tetris pays more for bigger clears: roughly 100 points for a single, 300 for a double, 500 for a triple, and 800 for a four-line Tetris. Those base values are multiplied by your current level, and extra bonuses come from T-spins, back-to-back difficult clears, combos, and dropping pieces. That is why efficient big clears massively outscore many small ones.

What is back-to-back in Tetris?

Back-to-back, often shortened to B2B, is a bonus for performing difficult line clears one after another without an ordinary clear in between. Tetrises and T-spins count as difficult; a plain single, double, or triple breaks the chain. Each qualifying clear during a back-to-back streak earns roughly fifty percent extra points.

What is garbage in Tetris?

Garbage is unwanted rows of blocks, each with a single empty gap, that push up from the bottom of your well and shove your whole stack higher. In versus play an opponent sends garbage when they clear lines, and some solo modes start you with it. You get rid of it by clearing the rows, which usually means digging down to the gap.
