A Halfsies bonus round is a rare mini-game that shows up at the end of about one daily run in ten, either Quarters (three cuts into four equal pieces) or Small Change (one cut that slices off exactly 25%), and it can add up to 60 points on top of the normal 300.
One run in ten, the game hands you a different knife job. Here is what it wants and what it pays.
Most days in Halfsies are the same deal. Three hand-drawn objects, one line each, and the scale tells you how close to half you got. Then, once in a while, you finish your third cut and the screen says BONUS! instead of taking you straight to your score.
That is a bonus round. It can only add points, never take them, and it tests something the daily cuts do not.
The game rolls once, at the start of your run, with a 10% chance in total:
The roll is made on your device for your run. It is not tied to the day, so your friends will not all get one on the same morning.
The roll is also saved with your run. If you close the app halfway through and come back, you get the same result. Quitting and restarting will not fish up a bonus.
Bonus rounds can show up on your daily run and on a replay of today. Past days from the Archive never roll one.
The rule on screen is "Three cuts. Four equal pieces. No do-overs."
You get one object. Your first cut splits it in two. Your next two cuts each split one of those halves. If every cut is perfect, you end with four pieces of exactly 25% each by weight.
Weight works the same way it does in the daily game: by the drawn area of the object, so a thin handle counts for very little and a thick barrel counts for a lot.
The catch is that mistakes stack. Quarters judges you by your worst piece, and a bad first cut cannot be fixed later. Say your first cut lands 55/45. Even if you halve both pieces perfectly after that, you get 27.5%, 27.5%, 22.5% and 22.5%. The worst piece is 2.5 points off 25%, which is 90% accuracy before you have made a single error on cuts two and three.
If you miss the object entirely, nothing bad happens to your pieces. The game just waits. Miss eight times in a row and the round ends, and any piece you never cut counts as the lump it is.
The rule is "One cut. Slice off 25% by weight." The intro shows it as "Slice off a quarter. Leave the rest."
This one feels easy and is not. People are good at halves because halves are symmetric. A quarter has no mirror to lean on. You have to picture where one quarter of the weight ends, and on a lopsided object that is rarely one quarter of the way along.
Accuracy is based on how far your smaller piece lands from 25%. A 20% slice and a 30% slice are both 5 points off, so both score 80% accuracy.
Both games turn your accuracy into points with the same formula. Anything at 50% accuracy or below pays nothing. Above that, points climb on a curve, so the last few percent are worth the most. The top is 60 points.
| Accuracy | Bonus points | Small Change example (smaller piece) |
|---|---|---|
| 50% or less | 0 | 12.5% or less, or 37.5% or more |
| 70% | 10 | 17.5% |
| 80% | 22 | 20% or 30% |
| 90% | 38 | 22.5% |
| 95% | 49 | 23.75% |
| 100% | 60 | 25% exactly |
The curve is steep on purpose, so a coin-flip effort earns nothing. Going from 90% to 95% is worth 11 more points.
With a bonus, a single run can go past the usual 300. Your cut score is still the lighter half divided by the heavier half, times 100, for each of your three cuts. The bonus rides on top, so the most a run can total is 360.
On the leaderboard's daily view, the bonus is added as a separate tail on your row. Weekly and all-time totals already include it.
Replays of today can roll a bonus too, but replays never count on the board, so that one is just for practice. More on how runs are scored is in Halfsies Scoring Explained.
You cannot ask for a bonus round. The only way to see one is to keep playing your daily three. Play today's cuts in the browser, or on iPhone or Android.
About one run in ten. Each daily run has a 5% chance of Quarters and a 5% chance of Small Change, rolled once when the run starts.
Up to 60 points on top of the normal 0 to 300. Accuracy of 50% or less pays nothing, and the points climb on a curve so that the last few percent pay the most.
No. The roll is random and saved with your run, so quitting and restarting will not get you one. Archive runs of past days never roll a bonus.
No. A bonus round can only add points. The worst result is zero bonus points.
It has been retired. Halfsies no longer judges any cut across more than one object, so the two current bonus rounds are Quarters and Small Change.
