Flash Count

A cloud of dots flashes for a moment. Type how many you saw. 3 clouds, scored on how close you get.

A cloud of dots appears for a moment, then it is gone. There is no time to count, so you have to trust your feel for quantity.

How to play

1. Press Show the dots. The cloud stays for a few seconds at most.
2. Type how many dots you think there were.
3. You then see the real number. There are 3 clouds, each spread differently.

Scoring

Each cloud is worth up to 333 points. 10% off gives 213, 25% off gives 83, and half off or worse gives 0.
