Moonwall: Number Loop Puzzle

Connect the clues. Close the wall. Let the moonlight in.

Moonwall is a calm number loop puzzle about building one continuous wall around a moonlit courtyard. Read each number, draw the exact number of surrounding wall segments, and make a single loop with no branches or breaks.

Start with clear 4×4 boards, then move into larger courtyards with hidden clues and more room to reason. Every stage has one verified solution.

Features
• 500 handcrafted-feeling, deterministic logic puzzle stages
• Gentle difficulty curve from 4×4 to 6×6 boards
• Smooth tap and drag controls for drawing walls

• Optional, quiet return reminder you control

Numbers show how many of a cell’s four sides belong to the wall. A question mark means that cell has no number clue. Complete every visible clue while keeping the entire wall connected as one closed loop.

Take your time, follow the moonlight, and solve the next courtyard at your own pace.
