Lassoar

A puzzle a day keeps the brain in shape. Lassoar is Slitherlink, the classic loop puzzle: draw one closed loop along the dots so that every number touches exactly that many loop sides. Every Lassoar puzzle can be solved by pure reasoning. There is never a guess, and every board is graded by the hardest technique it needs, from easy corner counting to long chains of consequence. ONE LOOP A DAY A fresh daily puzzle on a weekly ladder: gentle on Monday, master on Sunday. Keep a streak going (one slip a week is forgiven), race the day's leaderboard through Game Center, and share a spoiler-free result card that challenges a friend to beat your time. HINTS THAT TEACH Stuck? A hint shows the next deduction, highlights the corner or clue it uses and names the technique. You learn the patterns instead of getting the answer. MADE FOR THE PHONE Tap a side for a line, again for a cross, drag along the dots to draw. Crosses fill in automatically around finished clues. Undo, check for mistakes, pick up where you left off, and sync progress between your devices with iCloud.
