Cut the shape in half
One straight cut. Two equal halves? Cut in Half is a free cutting game that tests your eye for area. Drag a line across an everyday object, release, and watch the pieces separate. Aim for a 50/50 split.
A game is five objects, from a pear to a watering can. Each cut earns up to 100 points, for 500 in a game. Press Play again for a fresh set of five.
How to play Cut in Half
- Look at the whole shape. Judge how much filled area lies on each side of your planned cut.
- Draw one straight line. Start outside the shape and drag all the way across it. You can cut at any angle.
- Release to cut. The pieces move apart and show their percentages. A dashed coral line shows an even cut at the same angle.
- Finish five rounds. Go to the next object, build your total, then play again.
On a phone, drag with one finger. On a keyboard, focus the play area: Left and Right turn the line, Up and Down move it, and Enter cuts. Escape clears the line.
Scoring: how even was your cut?
The closer both sides are to 50%, the higher the score. A split shown as 50.0% / 50.0% earns 100 points. Points fall quickly as the pieces become uneven, so a careful adjustment makes a difference.
| Split | Points |
|---|---|
| 50% / 50% | 100 |
| 49% / 51% | 92 |
| 48% / 52% | 84 |
| 45% / 55% | 60 |
| 42% / 58% | 38 |
| 35% / 65% | 0 |
A 49% / 51% split is one percentage point from an even half. Both sides are treated equally: swapping the smaller and larger piece gives the same score. A 35% / 65% split or wider earns zero.
Look for area, not the halfway mark
A pear is much wider at the bottom than at the top. A line halfway up its height leaves most of the area below it. Move the cut toward the wider part to balance the pieces.
Handles, tails and stems can fool your eye in the other direction. A long, thin part may add little area; a short, broad part can add a lot. Picture the shape as a few simple blocks, then compare how much of each block falls on either side.
Holes are empty. The space inside a handle does not count toward either piece. Fine lines and dots help you recognise the object and do not change its measured area.
Learn from the dashed line
After each cut, the coral reference shows where a parallel line would split that object evenly. Notice which way it moved: toward the bigger piece. That is the adjustment to look for next time.
There can be many correct cuts through an irregular shape. You do not need a line of symmetry or a particular angle. You need equal filled areas on both sides.
Questions about Cut in Half
What counts toward the area?
The filled silhouette, including stems, tails and handles. Open holes stay empty. The game draws and measures the same outline.
Why did my line not cut?
Both ends need to be outside the shape, and the line must cross it. A short drag, a line that misses, or one that stops inside the shape leaves the round open so you can try again.
Can I play more than once?
Yes. Play again starts another five-object game. There are 25 original silhouettes, and the game favours objects you have not seen recently. Some appear facing the other way.
