About this game

Every grid is solvable by logic alone. No guessing. Keep your streak alive.

Deducto is an endless deduction puzzle. Each grid hides a number of hazards, and every number you uncover tells you how many of them sit in the eight squares around it. Read those numbers together and you can work out exactly where every hazard is.

The difference from a classic minesweeper is small to describe and changes everything to play: you are never asked to guess. Before a grid reaches you, a solver works through it using logic alone. If it cannot be finished without a coin flip, that grid is thrown away and another one is built. So if you are stuck, you have missed something. That is a promise the game keeps on every single puzzle.

HOW IT PLAYS

Tap a square to open it. Long press, or right click, to flag a hazard. Tap a number that already has the right count of flags around it and the rest of its neighbours open at once. Your first square is always safe, and it always opens an area to start reasoning from.

Solve a grid and your streak grows. The grids grow with it, from a gentle six by six up to twelve by twelve with more hazards packed in. Hit a hazard and only the streak counter resets. Your statistics, your themes and your record stay exactly where they were.

WHEN YOU GET STUCK

Hints are earned, not bought. Every three solved puzzles gives you a hint token, plus a bonus when you finish a grid without a single misplaced flag. Spend a token on a short code breaking round: guess four colours in six tries, and cracking the code reveals a move the game can prove is safe. Rather skip the minigame? Watch a short video instead and the next move is pointed out straight away.

WHAT YOU WILL NOT FIND

No pay to win. Nothing you can unlock changes a puzzle or makes a grid easier, because the only rewards are colours to look at. The game does show ads between puzzles, kept to a limit so that they never land in the middle of your thinking, and never straight after a new personal record.

Deducto is for anyone who likes minesweeper but hates losing a perfect run to a fifty fifty guess at the very end. Every grid is fair. Every grid can be reasoned out. The only question is whether you spot it.
