Christmas Blocks

Christmas Blocks brings the familiar falling-block puzzle into a festive winter setting. Shapes descend into a waiting grid, and your task is to arrange them so filled rows disappear. The classic arcade rhythm comes from fitting each piece into the spaces left by earlier moves.

A useful twist lets you exchange the active shape for the upcoming one, giving you another way to handle an awkward drop. Planning that exchange can help complete rows instead of leaving small gaps that become harder to fill.

Use the Left and Right Arrow keys to position the falling shape.

Press the Down Arrow to increase its downward speed, or use Space to send it straight down and fix it in place.

Rotate clockwise with the Up Arrow or X, and rotate in the opposite direction with Z.

Use the piece-exchange option when the next shape suits the open spaces better.
