Streak brains: what the size tells you
Next to your streak is a small brain. Its size and its colour are two separate pieces of information. This page is about the size, which tells you how hard the days in your streak were. The colour, which tells you how long it is, is on the metals page.
Seven sizes, one for each weekday
A brain's size follows the hardest weekday in your current streak. Monday is the easiest daily and Sunday the hardest, so the brain climbs through the week:
On screen the brains are drawn between 24 and 60 pixels wide, a little over double from the smallest to the largest. They are shown plain pink here because a streak shorter than a week has no metal yet.
Reading your brain
- A streak that is just Monday is the smallest brain. It is the start of something.
- A streak of Monday to Wednesday grows as the days get harder, ending at the Wednesday brain.
- A streak of Thursday, Friday and Saturday is only three days, but it includes a Saturday. Size follows your hardest day, not how many days you played, so a short run into the weekend still earns a big brain.
- Any streak that includes a Sunday gets the biggest brain.
Why a week always means the biggest brain
Here is a consequence worth knowing. A run of seven days in a row always contains one of every weekday, and so always contains a Sunday. That means every streak of a week or more has the biggest brain. From then on, the size stops changing and the colour takes over. The size is about the first week of your streak, the colour about everything after.
The size is a record of effort, not of luck
Because the size follows the hardest day, a streak cannot be inflated by playing only the easy days. Nor does it punish you for starting on a Tuesday. The brain simply reports honestly what you have solved, and it is worked out fresh from your history every time, so it can never get out of step with your calendar.
Where you will see it
- Beside your streak on the home screen.
- On the calendar, and on the calendar picture when you share it.
- When you finish a puzzle and the brain grows or changes metal, with a small celebration.
- In the help screens, in a table that shows the sizes side by side.
