How each kind of task works
The eight games fall into four kinds of task. Knowing what each kind asks of you makes the rules feel shorter and the results easier to read.
Recall: something shown, then gone
Flash Grid, Light Trail and Number Span all show you something briefly and then ask for it back: a pattern of tiles, an order of panels, a string of digits.
They adapt as you play. A right answer makes the next task one item bigger; a wrong one keeps the size or shrinks it a little and costs one of three lives. That is why these games end at different moments for different people, and why the result is the biggest thing you managed, not a count of rounds.
Each new task is drawn from the game’s seed together with the round and the size you reached. In a daily set or a tea set, two players who reach the same round with the same size see exactly the same task.
Focus: look closely, ignore the rest
Ink & Word, Odd One Out and Step Back ask you to hold your attention on one thing while something else tugs at it: the word under the ink, a sea of matching symbols, the item that came just before the one you need.
Two of them are timed differently. Ink & Word counts correct taps in forty-five seconds. Odd One Out counts the seconds you need for twelve rounds, so lower is better there. Step Back has a fixed length and scores how accurately you answered.
Numbers: a minute of sums
Quick Sums is the one game given over entirely to arithmetic. Your level decides the kind of problem, and the numbers grow a little each time you collect five more correct answers. No answer is ever negative or a fraction, which is why the keypad carries neither a minus sign nor a decimal point.
Speed: waiting well
Reaction Time measures the moment between a signal and your tap. The interesting part is the waiting: tap before the signal and it is a false start, and the wait itself changes every time so that rhythm cannot help.
Your device adds its own delay to every tap, which is why results are best compared on the same screen.
Reading your results
Every result card shows one main number, your best at that level and a small chart of your last results. The chart always draws better as higher, even for times. Days in a row and finished daily sets are counted too, and all of it stays in your browser.
