What makes a good brain game

A good brain game is won by thinking, not by fast fingers. You look at the board, work out what has to be true, and make the move that follows from it. Many of the puzzles here are checked so that there is exactly one answer, or so that every deal or level can be solved, which means a careful player can always find the way through without guessing.

That covers a wide range. There are number and logic puzzles such as Sudoku and Minesweeper, word games, patience card games, classic board games against a computer opponent, mahjong, escape rooms and puzzle boxes, and slower strategy and tycoon games where you plan a railway or a trading route. There are also calm learning games for children, from counting to telling the time. Most of them let you stop and think for as long as you like.

Brain games to start with

If you like numbers and logic, start with Sudoku, which has four difficulties and a hint that names the deduction instead of just filling the square. Minesweeper always makes your first click safe, and every number tells you how many mines touch it. 2048 has you slide and merge tiles towards a 2048 tile, with an undo for the move you regret. Picture Cross turns number clues into a hidden picture.

For words, Five Letters gives you six tries at a hidden word, Honeycomb asks for every word of four letters or more that uses the middle letter, and Maths Blitz runs quick sums from adding inside twenty up to percentages. Card and board players can pick FreeCell, where every card is face up from the start, or Chess, with every rule, a real engine at Easy, Normal and Sharp, and forty mate-in-one and mate-in-two puzzles. Reversi has twenty-four puzzles that each have a single best stone.

If you want something to work out over a longer sitting, Locked Room has twelve escape rooms with picture clues and no timer that ever ends your game. Lockbox Lab is thirty mechanical puzzle boxes, each with its own mechanism. Laser Maze asks you to turn mirrors until the beam lights every sensor, and Steam Rails lets you lay track and run trains between towns and works.

Taking your time, on any screen

Most brain games are played with a mouse or a finger. You click or tap a cell, a card or a tile, and drag where a game needs it, such as moving cards in FreeCell or laying track in Steam Rails. Many also work from the keyboard: in Sudoku you pick a cell with the arrow keys and type 1 to 9, and in the word games you type the word and press Enter. H shows a hint and U undoes a move in a lot of them, and P pauses.

On a phone or tablet, the controls switch to touch. Minesweeper has a flag mode for marking mines with a tap, and Sudoku gives you a row of numbers to tap. Because there is rarely a clock, these games suit a few minutes at a time: Sudoku keeps the current puzzle in your browser, so you can close the page and pick it up again later.

Frequently asked questions

Are the brain games on Kiloo free?

Yes. Every brain game on Kiloo is free to play in your browser. There is nothing to download or install and no account needed. Best times, high scores and solved puzzles are kept in the browser you play in, so you can come back and carry on.

Can I play brain games on my phone or tablet?

Yes, every brain game on this page works on phones and tablets as well as on computers. You tap cells, cards and tiles instead of clicking, and drag where the game asks for it. Word games show letters to tap, and Minesweeper has a flag mode built for touch.

Which brain game should I start with?

Sudoku is a good first choice: pick the easiest of its four difficulties and use the hint when you are stuck, because it explains why a digit fits. If you prefer words, try Five Letters. If you like cards, FreeCell shows every card face up from the start.

Do I need to play fast?

Usually not. Most brain games here have no time limit, or keep a clock only for your best time. Locked Room has no timer that ever ends your game, and Mahjong Garden has a Relaxed mode with no clock. A few, such as Maths Blitz and Lightning Quiz, are built around a timer on purpose.

Are there brain games for children?

Yes. The learning games are made for younger players: Memory Zoo is a calm memory game for ages four to ten with no reading needed, and Shape Sorter covers shapes, patterns and pictures for the same ages. Clock Shop and Letter Catch have no timers and no failing, and Number Garden has no way to fail.
