Shadows

LucidGrid Shadows is a distinctive number-logic game where every building changes the pattern of light and shadow. Place building heights into the grid so that every row and column contains each height exactly once. Then use the clues around the edge of the board to work out whether the buildings cast the correct shadows. Each puzzle can be solved through logic alone. No guessing is required. START SIMPLY, THEN MASTER THE SHADOWS Begin with approachable 5×5 puzzles, then progress to larger and more challenging 6×6 grids. Harder puzzles provide fewer edge clues, asking you to combine several deductions before placing the next height. PLAY YOUR WAY • Six handcrafted puzzles across Easy, Medium and Hard difficulties • A Daily Shadow challenge with local streak tracking • Optional hints when you need a carefully chosen next step • Automatic checking for duplicate heights and incorrect shadow clues • Undo and reset controls • A live timer that pauses when the app is in the background • Automatic saving and resuming of unfinished puzzles • Completion statistics, best times and hint records • Light, dark and system themes • Higher-contrast and larger-text options • Optional haptic feedback • Screen-reader descriptions for cells and clues CLEAR, CALM AND FOCUSED LucidGrid Shadows is designed around an uncluttered board and straightforward controls. Tap a cell, choose a height and gradually reveal the only arrangement that satisfies every clue. Incorrect duplicate numbers are clearly highlighted, while completed lines with an incorrect shadow result receive a separate warning. You can therefore see what kind of rule needs attention without being shown the answer. A NEW DAILY CHALLENGE Return each day for a deterministic Daily Shadow puzzle. Complete daily challenges to build your local streak and track your progress over time.
