Panes are pushed up into the wall from the bottom every few seconds. Line up three of the same colour — across or down — and they shatter, and every pane you clear buys the wall back a little space. The run ends when the wall reaches the top of the window.
You have two moves, and the whole game is the choice between them. SWAP trades the pair under your cursor: instant, but it only reaches the bottom two rows. CARRY lifts a pane clean off the wall so you can set it down in any column — slower, but it finishes patterns swapping never could. Lifting a pane out of the middle of a column also makes everything above it fall, which very often lines up a second match for free; each clear in a chain is worth more than the one before it.
Every 800 points the wall pushes faster and a new colour joins the glass — three colours at the start, six by the time you are deep in a run. Your best score is saved locally.
It is a match-three puzzle built like a stained-glass window.
Line up three of the same colour — across or down — and they shatter, and every pane you clear buys the wall back a little space.
A decent game for taking a break from daily routine and playing a little.
