Pocket Deduction

You wash ashore with a notebook, a pencil and three days of supplies. Inland, a lighthouse stands dark. If you can light it, someone will come. Pocket Deduction is a calm puzzle game about reading clues carefully. Every clearing can be solved by reasoning alone — there is never a blind guess, never a coin flip, never a timer counting down on you. Read the ground Numbers count the hazards in the tiles around them. Work from what you know, mark what must be dangerous, uncover what must be safe. Later islands add survey lines that count a whole row or column at once, so two kinds of clue describe the same ground. A journey, not a level select Three islands, thirty-six clearings, and a field diary that fills in as you go: the wreck you came from, the steps worn into a hillside, a keeper's cottage standing empty, a boat holed and dry in a hidden cove. Each island ends at a lighthouse. Light all three and you are found. Made for a slower moment No timers. No energy meters. No forced advertisements. Play a clearing on a bus or spend an evening on an island — your progress is saved on your device either way. A hand when you want one Stuck? Ask for an explanation and the game shows you which clues prove the next move, in plain words. Three per island, so help is always there without solving the game for you. Endless and daily When you want more, Endless generates a fresh clearing every time, with a harder one every fifth. The Daily survey is the same board for everyone in the world that day. Modes The Modes tab opens new ways to read the ground. Beacons count their whole row and column. Tides count only their four diagonals. Night brings both together. Same calm logic, new clues to master, and every mode can be tried for free. Plays anywhere The puzzles work completely offline. English, German, Spanish and Russian. Dark mode, a calm original soundtrack, gentle sounds, optional vibration, and a minimal view that hides everything but the board. Full Expedition One optional purchase unlocks every mode (Beacons, Tides and Night), Endless, unlimited field supplies and unlimited explanations, forever. No subscription, no consumables, nothing to buy twice. Made by Little Lighthouse Games.
