How do players clear the block board?
A full row or a full column disappears after a piece completes it. Clearing multiple lines at once brings combo bonuses, so a player may leave a nearly finished line open while placing another shape. The grid becomes tighter as open spaces disappear.
What is the ghost placement preview?
Before a shape lands, a faint preview shows where it would sit on the board. That gives the player a chance to spot a bad fit before committing the move. Dragging pieces from the three-slot tray also keeps the available choices visible.
Can I continue a puzzle later?
The current board saves automatically and offers a continue option. A player can pause a run without losing the arrangement already made, then return to the same set of open spaces. That makes this slower placement puzzle work well for short breaks on a phone or computer.
