A nine-year-old is trying the same Tower of Hanoi level for the fourth time. A disc goes to the wrong peg, she takes it back, stares at the screen for a moment, then starts over. From the outside, she's just playing. What she's actually doing is planning, spotting her own mistake and not giving up. That's the real value of brain games for kids: not "boosting" intelligence, but giving them an easy excuse to practise skills like these.
What brain games do and don't do for children
Let's start with the honest answer. Getting very good at a game usually means getting very good at that game. The most consistent finding in research is that children improve at the skill they practise. A child who plays memory cards gets faster at memory cards. How far that carries over to maths grades or general intelligence is debated, and the promises made for products sold as "brain training" tend to run ahead of the evidence.
That doesn't make games pointless. Some benefits don't depend on the game itself and travel easily into everyday life:
- Keeping going when stuck. Learning in a game that failing a puzzle isn't the end of the world, and that the way forward often appears after a five-minute break, is far less painful than learning it over homework.
- Thinking before acting. In puzzles like Tower of Hanoi or water jugs, random moves don't work. Kids notice that without anyone telling them.
- Holding attention in one place. Spotting differences or searching for words takes focus, even if only for a few minutes.
What matters most is that a game stretches a child a little without overwhelming them. Too easy, and it's boring in five minutes. Too hard, and it feeds the "I can't do this" feeling. A good choice is one made for the child's age and for the child.
Choosing brain games by age
The groups below are a rough map. A child who reads early or loves puzzles can easily move up a group, and the reverse is fine too. You know your child best.
Ages 4–6: the table before the screen
At this age, the best brain games are mostly off-screen: jigsaws, matching cards, sorting by colour and shape, simple board games, anything that gets hands and eyes working together. If they do play something on a screen, pick games whose rules fit in one sentence and need no reading. A memory cards game with only a few cards is a reasonable start, especially with an adult nearby.
Ages 7–9: games with rules
Once reading settles in, the options open up. Word games do two jobs here: they're fun, and they build a habit of playing with letters and syllables. Word search and hangman are big favourites at this age. In hangman, kids start working out which letters turn up most often, and why guessing vowels first makes sense, without anyone explaining it.
For visual attention, spot the difference works well; for direction and planning, try maze escape. Instead of giving a hint in a maze, asking "what if you looked backwards from the exit?" shows a child a new way of thinking.
Ages 10 and up: real puzzles
By now, children are ready to think a few steps ahead, and classic logic puzzles start to make sense. Tower of Hanoi teaches breaking a big job into smaller ones: to move five discs, you first have to work out how to move four. The water jug puzzle needs both logic and simple arithmetic. Lights Out makes you think about moves that change more than one thing at once.
For kids who like strategy, the apple logic game is a nice example. It's a version of the classic game of Nim: you take turns picking apples, and whoever takes the last one loses. A child will probably lose the first few games, then start to sense there's a pattern. The moment they find it themselves is the best part of the game. You can play the same thing at the table with matchsticks or dried beans.
Kids who get on well with numbers can also try fast math and Shikaku. One thing to watch: timed games stress some children out. If yours freezes as the clock ticks down, stick with untimed puzzles for a while.
Screen-free games do the same job
A game doesn't need a screen to count as a brain game. Chess, draughts, mancala, building something with Lego without the instructions, card games, even "I'm thinking of an animal" on a car journey all exercise the same skills. And most of them are played with someone else, which means learning to wait your turn and to lose.
A practical balance: keep screen games short and focused, and leave the longer play sessions for the table. Let the screen puzzle be something the child can work on alone, and the table game a shared family moment.
Small habits that make play more useful
The same game can have very different effects depending on how it's played. A few habits make a difference:
Ask, don't solve. Instead of "put that disc there," try "which disc can you move now?" It leaves the thinking with the child. When they try to explain where they're stuck, they often find the answer themselves.
Praise the effort, not the brain. "You tried that level three times and finally got it" tells a child what actually worked, in a way "you're so clever" doesn't. Researchers still argue over how big the effect of this approach is, but at the very least it doesn't give a child a reason to avoid hard puzzles.
Keep sessions short. A fifteen- or twenty-minute puzzle session is usually more productive than an hour of level after level. Tired kids make mistakes, mistakes make them bored, and the fun goes out of it.
Leave room to lose. Losing to the computer at the apple game may be the only reason a child starts thinking about strategy. Helping them win every time takes that chance away.
If you want to measure something
Some parents want to go a step further and measure their child's intelligence. Our IQ test and quick IQ test are designed for adults and won't show a child's real level. A formal assessment for children can only be done with tests given by a trained psychologist; we explain how that works in How Do You Find Out Your IQ? Most children don't need one. A child who's curious, asks questions and tries again when stuck is already in a good place.
Not sure where to start? Look through the brain games list together with your child. Whichever one they pick will already tell you something about what they enjoy.
