Drag, swap and fuse. Restore the glowing windows.
Glowpane Puzzle is a relaxing jigsaw puzzle game in a stained glass style for phones, tablets and computers. Every level is a glowing picture cut into square glass pieces: drag one piece onto another to swap them, and pieces that end up next to their true neighbours fuse with a line of light and move as one group. You get a finished game with 50 levels, a chapter map, saved progress, music and sound effects, plus the complete source code to change the pictures, translate and publish as your own.
Drag, swap and fuse
Drop a piece on another and the two change places. When a piece lands next to the right neighbour, both fuse into a group that moves together, so the window comes back piece by piece. Every level has a par, the fewest moves: finish at or under par for 3 stars and an extra hint. Captions on the first levels teach the rules in one line each.
50 levels in 5 chapters
Spring Meadow, Coral Lagoon, Autumn Woods, Winter Night and Golden Savanna, 10 stained glass pictures each, with grids that grow from 2×2 to 6×6 and bigger windows on the 5th and 10th level of every chapter. The level map has one page and its own background per chapter, with arrows and side swipe; locked chapters can be viewed before they open. A rose window on the home screen lights one petal per finished level.
Hints and Peek
The player starts with 3 hints, and every 3-star window gives one more. A hint makes one correct move. Holding the Peek button shows the whole finished picture on the board. On phones and computers, upright or sideways: turning the device during a level rearranges the grid and keeps the moves already made.
One picture = one level
Levels come from a simple list of pictures in assets/levels.json. Add your own photos or drawings, create new chapters, set the map background of each chapter and reorder levels without writing code. Any picture size works: the game crops the centre to each grid.
