Yodoku

Bring light to a quiet world of logic.

Yodoku is a lantern-placement puzzle with four simple rules:
• Place exactly one lantern in every garden bed.
• Place exactly one lantern in every row and column.
• Keep lanterns from touching, even diagonally.
• Mark impossible tiles until the answer becomes clear.

Begin with a guided first garden, then work through 9,999 carefully paced puzzles, from compact 4×4 boards to intricate 10×10 layouts. Every garden has one unique solution and can be solved without guessing.

Think at your own pace:
• Swipe to mark tiles.
• Hold or double-tap to place lanterns.
• Ask for a logical hint when you get stuck.
• Undo moves and resume unfinished gardens.
• Track flawless solves and improve your personal score.
• Play offline with progress saved on your device.

The campaign mixes square boards with corner cuts, edge bites, chamfers, and courtyards. Light, dark, and system themes let the gardens settle into your space. Optional connected colors, reduced motion, original wooden-mallet sounds, and tactile feedback put the finishing touch on every move.

No countdowns. No pressure. Just you, the gardens, and one lantern at a time.
