Tetr io

Falling blocks leave no room for delay. Tetr io gives the old-school puzzle format a sharper feel, with fast response, exact movement, and none of the drag that breaks a stacking rhythm. Traditional row-building stays intact, yet the added system depth changes how each drop reads on the board. Piece placement feels exact from the first second. Input delay doesn't get in the way, and missed movement never comes from sluggish response.

How to play?

Place each falling shape into the stack, filling horizontal rows from edge to edge until the completed row disappears. With little time to hesitate, read the next position fast and slide, rotate, or drop the piece into a gap that won't leave awkward holes. Full rows remove stacked space and extend the run. A tight fit creates better setups for the next piece, pushing the board toward longer chains of row removals.
