Snowcork

Snowcork is a calm number logic puzzle set on a frozen lake at dusk. Every pond is a square sheet of ice where each drilled hole carries a depth number. Plug surplus holes with snow corks until no depth repeats in any row or column. Two corks may never sit side by side, and the open ice must stay in one connected piece. Tap a hole to cork it, or switch to Chalk to mark holes that stay open. Each pond has exactly one solution, and a wrong cork cracks the ice; three cracks thaw the pond. Forty-eight ponds wait across four chapters, growing from 4x4 to 7x7 boards. Earn up to three stars per pond, beat your best time and light the warden's lantern once per pond for a hint. The Warden's Almanac explains eight solving techniques, each with a small practice board. The game works offline, and your stars, best times, unlocked ponds and Almanac cards stay saved on your device. Pick up an unfinished pond where you left it in Snowcork.
