How are the falling shapes selected?
The game shuffles a bag containing seven shapes and draws from it, so each type appears before the bag begins again. This avoids long stretches without a needed piece. The ghost outline also shows where the active shape would land if dropped now.
What does a soft or hard drop do?
A soft drop moves the shape downward with player control; a hard drop sends it to the landing point at once. Clearing rows earns points, and clearing several together pays more. Rising levels shorten the time available to adjust a piece.
Can the game be played without a keyboard?
Yes. The sample has full touch controls alongside keyboard play, so it can work on a phone as well as a computer. A founder adapting a falling-block game should make rotation and placement easy to reach without covering the part of the board the player needs to watch.
