On the Subject of Pentomino Puzzle

Pretty puzzling!

• The module will have a screen with a 10x8 grid. The bottom six rows are the area that needs to be filled. Doing so will automatically solve the module. On the grid are twelve pentominoes that are randomly placed (but never close to a solution).
• Pentominoes have different colours. If a pentomino crosses over another pentomino, the grid space will turn grey. A grid space not filled in is black.
• Selecting a gray space will select the top-most pentomino in the stack, or cycle through the stacked pentominoes if a pentomino is selected in the corresponding stack.
• The arrows move the selected pentomino, the ↔ and ↕ symbols flip the selected pentomino and the oval will rotate the selected pentomino 90°.
• Any solution is valid, and it is not possible to get a strike.
