Line Cluck Drop

Below the main field, three block figures wait for action. Each one occupies a certain number of cells in a fixed arrangement. You drag a figure upward onto the board and position it over empty cells. When you let go, the figure locks into those cells permanently unless cleared through line removal.
After every placement, the board performs a line check. Rows are scanned from left to right. Columns are scanned from top to bottom. Any row that is completely full of blocks vanishes. Any column that is completely full of blocks vanishes. Vanished lines free up cells. The blocks remaining above a cleared row fall downward to fill the vacated space. Points accumulate based on the number of lines removed in that single check.
You can remove multiple lines at once. Two rows and one column cleared in the same move earns more than clearing a single row alone. The point reward scales with the total number of lines cleared.
The shape pool stays at three. Using one shape removes it from the selection. A new shape spawns in its place. You always have three options to choose from, but the specific shapes are generated randomly.
The available grid space shrinks over time. Even with line removals, the board tends to fill faster than it clears. Eventually, the open areas become too small or too fragmented to accommodate any of the three available shapes. At that moment, the game halts.
When the session ends, the score screen appears. A hen is positioned on a path at the bottom. The score begins counting upward. As it counts, the hen steps forward along the path. Each step corresponds to a portion of the score. When the score finishes counting, the hen stops at her final position. Her location reflects your performance. No additional rewards, no bonus animations. Just the walk.
