SlitherDaily: Loop Puzzle

One loop. The right numbers. A fresh logic puzzle every single day.

Slither Daily brings Slitherlink — the elegant Japanese loop puzzle — to your daily routine. Connect the dots into a single closed loop where every number tells you exactly how many of its four sides the loop uses. Simple rules, deep deduction, and a satisfying click when the last edge falls into place.

FIVE PUZZLES EVERY DAY

• A new set drops daily, from a one-minute Easy to a chewy 8–12 minute Master
• Everyone gets the same puzzles each day — compare times with friends
• Every puzzle is computer-verified to have exactly one solution. No guessing.

BUILT FOR THINKING

• Tap to draw an edge; switch to the X tool to mark edges that are out
• Numbers turn grey the moment a cell is satisfied, red if you've over-drawn
• Unlimited undo and a clean board that reads beautifully in light or dark mode

KEEP YOUR STREAK

• Track your daily streak and best times for every difficulty
• Pick up exactly where you left off — your progress is saved automatically
