How to play Butterflinch
Read the rule on the card, then press Space, or tap or click anywhere, to start the slice. It starts by itself after a few seconds.
Wait while the lights are down: a twitch, a ding, a hop or the wrong bread is not the pop.
When your bread pops, the board turns yellow and its name fills the top: press as fast as you can.
Ten slices, then your results: each slice's time in ms, your average and best, and what caught you.

Tips
Read the rule before you start the slice. It always says which bread or which pop counts, or which bread does not.
Do not guess. A press before the pop, or within 100 ms of it, costs the whole slice, and a fast catch is only worth a little more than a steady one.
When a bread pops, read the big name at the top before you press. The wrong bread has its own name too.
Rest a thumb on Space, or a finger on the screen, before you start a slice, so your hand is already there when it pops.
About Butterflinch
Butterflinch is a daily reaction time game with one toaster and one button. Ten slices, one try a day and the same ten slices for everyone, new every midnight New York time. Each slice puts one short rule on the screen, the lever goes down and the lights go out. When the toast pops the whole board turns yellow, and you press as fast as you can. Your time comes up in milliseconds and the slice flies into the rack.
The first three slices are a plain reaction time test, so anyone can play from the first second. Then the toaster starts to play tricks, and every day brings its own: its own special, its own toaster habits and its own basket of breads. One day the lever twitches and smoke puffs out of the slots; another the bell on top dings and the whole toaster hops. The wrong bread pops first, a scone when the rule said pita, with its name in big letters so you can tell at a glance. Some days the toast pops twice, or three times, and only the last pop counts. The final slice puts three tricks and the real thing in a row.
Getting caught never ends your run. A press on a trick or too early costs that slice's points, the raw slice lands on the glass with a FALSE START stamp, and the next slice starts. A press under 100 ms counts as too early, because that is a guess, not a reaction. Faster always scores more: up to 1,000 points a slice, so the perfect day is 10,000. A catch in 250 ms or less is stamped GOLDEN, in 400 ms or less CRISP. Equal scores rank by the total time you took on the cues, so the quicker hands come first on the day's leaderboard.
Times are counted the way the game is verified: in whole steps of 1/60 of a second, about 17 ms, the same for every player. Every leaderboard score is checked by replaying the run on our servers. Your device adds its own delay too, so a phone may read a little slower than a mouse. For a precise, unlimited test with no tricks, try the free reaction time test; Butterflinch is the daily game with the catches.
It plays on phones, tablets and computers with one button all the way through: press Space, or tap or click anywhere. Every slice only asks when to press, never where, so you can play the whole game with a thumb resting on the space bar. Nothing on screen strobes or flickers: the board changes from dark to bright at most about once a second. The cue is something you see (it makes no sound at all), and every bread has its own shape and its name in big letters, so the game never asks you to tell colours apart.
If you like it, there are more reaction games and timing games, and the other daily games reset at the same time. One try a day, so make it count.

Butterflinch FAQ
How long does Butterflinch take?
About a minute and a half for ten slices. Each rule card starts itself after a few seconds, so it never waits for long.
Is it the same for everyone?
Yes. Every day at midnight New York time there are ten new slices, the same for every player, and you get one try. The Daily deals its own set from a separate stream.
Is it different every day?
Yes. Every day brings its own special trick, its own three toaster habits and its own basket of four breads, in its own order, and no day's ten slices come back within a year. The first three slices are always a plain reaction test, so every day starts easy.
Do I need anything but the space bar?
No. Every slice is one button: press Space, or tap or click anywhere. No slice asks you to aim or to choose a side, only to press at the right moment.
What happens if I get caught?
That slice scores nothing, the game shows you what caught you, and the next slice starts. There are no lives, and every slice is played.
How precise are the times?
They are counted in whole steps of 1/60 of a second, about 17 ms, because every score is checked by replaying the run on our servers. Your screen and your mouse or touchscreen add their own delay, so compare times on the same device.
Is Butterflinch a reaction time test?
It is a daily reaction time game. The first three slices are a plain reaction test, then the toaster starts to play tricks. For a plain test you can repeat as often as you like, with your average and best in milliseconds, take the free reaction time test.
Can I play with the sound off?
Yes. No slice needs sound: every cue is something you see, and the cue itself makes no sound at all.
Is it safe if flashing lights affect me?
Nothing strobes or flickers. The stage changes from dark to bright at most about once a second, well below the three flashes a second that accessibility guidelines warn about. The changes are still sudden, so if you are unsure, check with your doctor.
