What makes a good logic puzzle
A logic puzzle gives you a small grid, a handful of rules and one hidden solution. Everything you need is on the screen. You do not need math, trivia or luck: only careful reasoning, one deduction at a time. That is what makes these puzzles so satisfying. Every correct cell you place is something you have proven.
The puzzles on this page come from two sources. Some are our own games, such as Queens, Tango, Zip and Star Battle, built with big, tappable tiles and smooth animations. Others use the renowned open-source puzzle collection by Simon Tatham, which has refined classics like Nonograms, Slitherlink and Hashi for more than twenty years. All of them generate fresh boards, so you will not run out.
How to choose a puzzle
- Short and relaxing: Queens, Tango and Zip take two to five minutes and teach you the basic tricks of logic puzzles.
- Line-by-line logic: Nonograms ask you to shade cells so every row and column matches its number clues. Satisfying, calm and never needs a guess.
- Classic deduction: Minesweeper, Tents and Akari are about reading numbers and ruling out cells.
- Loops and paths: Slitherlink and Masyu ask you to draw a single loop. They are harder to learn but very elegant.
- Region puzzles: Star Battle, Shikaku, Hitori and Mosaic are about dividing or shading a grid under strict rules.
- Sort and move: Water Sort, Ball Sort, Tower of Hanoi and the Sliding Puzzle are about planning a sequence of moves.
- Code breaking: Code Breaker asks you to deduce a hidden color code from clues, in as few guesses as possible.
General solving tips
- Start where the rules bite hardest. A row with only one free cell, or a region of size one, usually gives you your first sure move.
- Mark what cannot be. Crossing out impossible cells is often more useful than placing pieces.
- Look for pairs. Two cells that must hold the same thing, or two regions that share a row, often force a deduction elsewhere.
- Never guess. If you are stuck, step back and check every rule against every line. There is always a next logical step.
Logic puzzles train patience, attention to detail and the habit of checking your assumptions. Above all, they are fun. Pick a puzzle above and start with an easy size.
Frequently asked questions
What are logic puzzles?
Logic puzzles are problems you solve by reasoning from a few clear rules, not by guessing or general knowledge. Each puzzle here has exactly one solution that you can reach step by step.
Which logic puzzle should I start with?
Queens, Tango and Star Battle are quick to learn and finish in a few minutes. Nonograms and Minesweeper are great next steps. Slitherlink, Masyu and Hitori are for when you want a real challenge.
Do I need to guess?
No. The puzzles are generated so that every cell can be worked out by logic. If you feel stuck, look for a rule you have not used yet, such as a full row or a region with only one space left.
Are the puzzles free and unlimited?
Yes. Every puzzle is free, needs no account and generates a new board whenever you want one.
