Slither Hole

Every snake is asleep in its burrow. Pull it out, one cell at a time, until every row and every column holds exactly the number it asks for. That is the whole game. No timers you have to beat, no lives to run out of, no move you cannot take back. Just a grid, a handful of snakes, and one answer that always exists and can always be reasoned out. You never have to guess. HOW IT WORKS • Tap an undecided cell to pull its snake out as far as that cell. • Tap a snake cell to net it instead — the snake stops short, and the rest of its path is netted behind it. • Tap a netted cell to clear it back to undecided. • A clue turns green when its line adds up, and red when you have overshot. Every level is generated fresh and verified to have exactly one solution before you ever see it. Nothing is hand-authored, so nothing runs out. PICK YOUR SIZE Boards run from a four-by-four you can finish on a bus to a thirty-by-thirty that will keep you company for an evening. Curved snakes wind around corners; switch them off and every snake is a straight run. Bigger boards pay more. COINS, RECORDS AND BADGES Finishing a board earns coins more for a bigger grid, more again for solving it with no help at all or inside the par time. A hint fills in one whole snake and a reveal finishes the board, and both cost coins, so taking help is a real decision rather than a free button. The game keeps your record book: puzzles solved, best time and fewest moves for every board size, longest run of clean solves, total time played. Sixty-two achievements and a shelf of leaderboards, if you like that sort of thing, and nothing that nags you if you do not. TEN BIOMES Meadow, Dunes, Tundra, Ice, Night, Ember, Neon, Candy, Abyss, Mono. Every tile is drawn live rather than shipped as an image, so switching biome is instant and the whole game board, menu, badges, the dust in the air — changes with it. A bone bleaching in the dunes, a doughnut dropped in the candy, sparks drifting through the neon. BUILT SMALL Under two megabytes. No advertisements. No in-app purchases. No account.
