Combo Atelier

Create a three-drop clearing combo in the atelier: three consecutive placed pieces must each clear at least one row. The six-piece queue is visible, and the Hold slot can save or exchange the active piece once before each drop. Move, Rotate and the landing ghost help fit the progressively wider gaps. A drop without a clear resets the combo; a multi-row clear counts as one combo step but scores every row times the new combo. One Undo can restore the last nonterminal drop, including its hold and queue state. Discard consumes the active piece and breaks the combo. Prepare the correct order instead of rushing the first shape into the well. Keyboard: Tab and Enter/Space operate buttons; R restarts.
