Cardfall Gambit

Clear three rows and earn four points before the six-piece queue runs out. Move and rotate the active piece, then Drop along the current gravity. Three single-use cards rewrite the well: Drill lets you tap a column to remove every block there; Double makes the next row clear worth twice its normal points; Flip reverses gravity and compacts every column toward the new ceiling or floor. Cards do not score for removed blocks. Ghost circles preview the landing when the spawn path is clear. Discard skips one queued piece without changing the board. Inspect the buried bottom gaps before casting: a blocker above them may prevent an otherwise perfect drop. Keyboard: Tab and Enter/Space operate buttons; R restarts.
