Opal Carrel

Opal Carrel is a casual sliding puzzle. Eight colored panes sit in a window, and one space stays empty. Tap a pane next to the gap and it slides straight into that space. A pane moves only up, down, left, or right. The small mark on a pane shows where it belongs. Read the window from left to right, then down. The empty space finishes at the end. Time left on the clock is added to the score when the window is whole. If the clock runs out first, the light fades. Later windows give less time. Glass painted on the wall is not a pane you can slide. This is a self-contained sliding puzzle. Nothing is wagered, and there are no cash prizes.
