Object: Catch all Butterflies.
 
First click anywhere on the board. Four Butterflies will appear. You are a biologist in the Amazon collecting Butterflies. You have to anticipate three times in a row where a butterfly will go in the next step in order to catch one. Yellow indicators on the left border count your successful predictions. Everytime you guess wrong, the trial-counter is reset to zero.
 
The trial-counter is also reset when you caught a butterfly. Indicators on the right border count the caught butterflies.
 
After a few clicks you will begin to understand the butterflies' flight pattern. If a Butterfly is aiming for an occupied square, it will miss a turn.
 
You win when you have caught all butterflies.
 
Variants: The flight patterns get progressively more difficult to predict. But they are never random; they always follow a simple fixed pattern that you have to find out.
 
Good luck!
 
 
I was once an avid Lepidopterist (butterfly collector). When I emigrated to New Zealand in 1986, I donated my collection of 500 different species to the Auckland Museum, where it still is their only European collection.
