A free block puzzle for kids — with no ads

How to play, and the scoring trick most people miss

Block puzzles are one of the few games that suit a young child perfectly: no reading required, no time pressure, no way to lose progress. The problem is finding one that doesn't interrupt them every ninety seconds.

The rules, in fifteen seconds

• You get an 8 × 8 board and three shapes at a time.
• Drag a shape onto any empty space that fits it. Shapes cannot be rotated.
• Fill a complete row or column and it clears, freeing up space.
• When all three shapes are used, three new ones appear.
• The game ends when none of your three shapes fits anywhere.

That's it. There's no timer, so a child can stare at the board for a full minute without being punished for it — which is exactly what you want if the point is thinking, not reflexes.

How the scoring actually works

This is where most players leave points on the table. Clearing lines together is worth far more than clearing them one at a time:

Two lines cleared together score 40. The same two lines cleared on separate turns score 20. So it is genuinely worth setting up a double instead of taking the easy single — and it's a nice, concrete bit of arithmetic for a child to discover on their own.

Simple strategy that works

1. Big pieces first. The awkward 3×3 square and long bars need open space. Place them while you still have room; the little ones fit almost anywhere.
2. Keep the middle usable. Building up along the edges leaves the centre open for bigger shapes. Filling the centre first is how boards get stuck.
3. Avoid single-square holes. One isolated empty square is very hard to use — only one shape fits, and it may not turn up.
4. Don't rush the clear. If a row needs two more squares and you can complete a column at the same time, the wait is worth 40 points instead of 20.
5. Keep streaks alive. Clearing on back-to-back placements adds a growing bonus, so a steady rhythm of clears beats one lucky big one.

Why so many kids' puzzle games are exhausting

Most free puzzle games make their money from advertising, which means the game is designed around the ad breaks rather than the puzzle. A child settles into concentrating, then a video appears, then a button they must find and close, then an offer to buy something. Younger children often can't tell the advert from the game, and tap it.

Is it actually good for them?

Let's be honest about this: it's a break, not a lesson, and nobody should pretend a block puzzle teaches the syllabus. What it does involve is planning a couple of moves ahead, judging whether a shape will fit before committing, and coping calmly when the board goes wrong. Those are decent habits, and they're the same ones that help when a maths problem doesn't work out first time.

Ten minutes between practice sessions is about right. It's meant to be the fun bit.
