About Tangram
Tangram is a free shape-fitting puzzle for kids. Each level shows a dark outline — an ice cream, a fox, a swan, a letter — and your child slides colored geometric pieces to fill it. It is the classic seven-piece set: two big triangles, one medium, two small, a square, and a parallelogram. The same seven pieces make hundreds of different pictures, so the constraint is the whole puzzle — you never get more pieces, you just have to think about which one goes where.
One thing is different from most tangram apps. The target is an outline only — no shading, no piece guides inside it. As each piece snaps home, the area it covers lights up, so the child is illuminating a shadow rather than coloring inside the lines. The picture was there all along, and they make it visible. The pieces sit in a numbered tray, not a scattered pile, so a 5-year-old is not overwhelmed on the first screen.
How to play
- Drag a colored piece from the tray onto the board.
- Tap the piece to rotate it 45 degrees.
- Double-tap the parallelogram to flip it.
- Wrong spot? Drag the piece back to its tray slot.
- Fill the whole outline, then tap Next for the following shape.
What it teaches
Underneath the sliding, your child is building spatial reasoning — the habit of mentally turning a shape to see how it fits. Each level rewards mental rotation (does this piece need a quarter-turn?) and part-whole thinking (two small triangles make a square; a square turned 45 degrees is a diamond). It is the cleanest way we know to practise the skill that maths, map-reading, and packing a school bag all quietly depend on. Early spatial skill is also one of the stronger predictors of later maths and science ability; the long-term research behind that claim, and why it matters at this age, is in Tangram for kids: a quiet spatial workout.
Frequently asked questions
What is Tangram?
A free shape-fitting puzzle game for kids. Each level shows a dark outline — a cat, a boat, a letter — and your child slides and turns a set of colored geometric pieces to fill it. It uses the classic 7-piece tangram: two big triangles, one medium triangle, two small triangles, a square, and a parallelogram.
How do you play Tangram?
Drag a colored piece from the numbered tray onto the board. Tap the piece to rotate it 45 degrees, and double-tap the parallelogram to flip it. If a piece is in the wrong spot, drag it back to its tray slot and try again. When every piece is placed, the outline lights up with a soft chime and a little win card appears — tap Next to move on to the following shape.
What age is Tangram for?
Best for ages 5 to 7. The first level (Ice Cream) uses just three pieces and needs no rotation, so a 5-year-old can start cold. The rotation gesture asks for a little fine-motor control, so under 4 is usually too early. An older child can keep going all the way to the abstract silhouettes near the end.
What does Tangram teach?
Spatial reasoning — mentally turning a shape to see if it fits, and breaking a whole picture into parts. Your child learns that two small triangles make a square, that a square turned 45 degrees is a diamond, and that a parallelogram flips. Spatial reasoning like this is a skill that maths, map-reading, and even packing a school bag quietly draw on, and a tangram builds it as a side effect of trying to make a cat.
Is there a timer?
No. Tangram is fully untimed — every level is play-at-your-own-pace. A child can stop, tilt their head, rotate a shape in their mind, and place it whenever they are ready. There is no clock, no rush, and no way to run out.
What happens if my child places a piece wrong?
Nothing harsh. A piece dropped in the wrong spot or the wrong rotation just stays where it lands — there is no red buzzer and no losing screen. To undo, drag the piece back to its slot in the tray. A miss on a level means retrying the same level, never dropping back to an easier one.
How many levels are there?
122, ordered easy to hard. It opens with three-piece shapes, then a geometric primer (square, triangle, rectangle), then recognizable objects and animals, then letters, and finally abstract full-tray silhouettes. Beat a level and a win card offers Next — the levels run in a fixed order, so there is no menu of levels to scroll, which suits pre-readers who cannot read one anyway.
Is Tangram free? Any ads or sign-up?
Yes, completely free. No ads, no account, no sign-up, and no data collected about your child's play. It runs in any browser and can be added to the home screen to play offline, which suits a long quiet puzzle session on a shared family phone.
