Memory · ~3 / 5 / 8 min
What you do
A short digit sequence, then one extra digit each time you clear a level. One miss ends the session.
Why it is useful
Hold a string, then a longer one, without writing it down. That is closer to keeping a headcode or a phone message than a trivia quiz.
Memory · ~2 / 3 / 5 min
What you do
A stream of letters. Was this one the same as two letters ago?
Why it is useful
Working memory under a clock. The cab is full of things you must keep and update while something else is happening. If the stream feels unfair, that is the point.
Memory · ~3 / 5 / 8 min
What you do
Hear a list once, then answer a question about it from memory.
Why it is useful
You will be told things once. The test is whether the list is still there when the question comes, not whether you can look back at a screen.
Memory · ~3 / 5 / 8 min
What you do
Watch blocks flash in order, then click the same sequence. One miss ends the session.
Why it is useful
Spatial memory, not digits. You have to keep a path in your head while the board is still in front of you. One miss and it is over, so guessing is expensive.
