Solve sea-glass logic puzzles and restore a sunlit island.

Isle of Glass is a logic puzzle game about dividing luminous mosaics into connected pieces. Drag through squares to draw a piece, or follow grid lines to split glass. Follow the clues, try your ideas, and find your own valid solution.

WATCH, THEN COPY An animated demonstration sits directly above your practice board. Watch one row, copy it below, then learn the next. Lift between pieces. Taps do not fill shapes or fix moves automatically. Skip or replay the introduction, use still steps, or try the button alternative. A short, skippable walkthrough introduces your first board's controls.

1,000 CAMPAIGN PUZZLES. 25 SHORES. Explore an original campaign across five island charts. Two short learning boards lead into puzzles with more pieces, irregular outlines, holes and fixed borders. Some boards ask for an exact number of pieces of each size. Restore each shore's shared mosaic to open the next path, or stay longer to earn silver and gold decoration. Discover hidden mosaics and unlock two bonus shores after the main journey.

FOLLOW THE CLUES Use the displayed set of allowed shapes, turning or flipping them to fit. Find the right area. Make rectangles and L shapes. Gather one star, or pair a sun with a moon. Read numbers that tell you a piece's size. Give neighboring pieces different sizes or different shapes. Squares across a fixed border must belong to different pieces. Your existing started and completed boards keep their previous layouts and rules.

32 MORE WAYS TO THINK Explore four optional collections of rule studies. Match a piece to an outline clue, give pieces across a marked edge the same shape, or gather one sun, one moon and one wave in every region. The Cutter’s Table asks for an exact number of each shape. Start with gentle introductions, then combine clues in harder studies.

ROOM FOR ANOTHER IDEA Pieces that need changing show a clear X. Undo, redo and Reset let you experiment. Borders and Pencil are optional tools. Browse shape details, check whether your pieces can lead to a solution, or reveal a possible next piece. Hints are free.

A LITTLE LIGHT FOR EVERY SOLVE Finish a mosaic for a brief celebration, then tap Next level when you are ready. A glass-window map opens each shore. Its puzzle grid shows completed panes and highlights the next playable level. Completed puzzles remain available for replay. Moving effects follow your iPhone's Reduce Motion setting.

YOUR PACE, YOUR COLORS Choose Sand, Chart paper or Deep water themes. Sand and Chart paper support System, Light or Dark appearance; Deep water stays dark. Optional local reminders can bring you back after time away. Let each new piece change color automatically, or choose a color and keep it. Colors never determine the answer. Higher-contrast glass and adjustable haptics are available in Settings. Solve a puzzle each day to build a streak, and open the home-screen calendar to see your completed days. Progress and daily activity save on your device.

The optional online community lets you download approved mosaics and submit your own designs for review.
