## Description

_ButterFlight_ is a strategy game where you must “collect” a certain amount
of butterflies.

The game presents you a 10 by 10 (or 9 by 9, depending on the game mode) big
playfield, randomly filled with different types of butterflies. Your job is
now to arrange at least three butterflies in a row, by simple exchanging the
position of two adjacent butterflies. Once three or more are in a row, they
fly away and new ones fills the gap. But you can only change position of
butterflies, which will then form a row; if this is not the case, you can’t
move them.

Depending on the game mode you play (4 different available), you have to make
horizontal and vertical rows, or vertical and diagonal rows. And the number of
butterflies you are rotating (two, three, or four) also depends from the game
mode.

Each level has an unique type of butterflies and a certain amount which must
be collected. Those are blocking the others, so you must plan which
butterflies you use for a row. Once all butterflies from this unique type are
on the playfield, all butterflies flying away, and you can proceed with the
next level.
