Game Tunnel - ButterFlight

You play on the glade that is filled with the multicolored butterflies. At every round, you have to collect a certain number of butterflies of a particular color on the glade. You can flip and rotate the butterflies sitting there - try to bring those of the same color together. They will fly away, freeing the place that will be filled with the new butterflies. There are four different game modes: Pairs, Twins, Quads and Triads.

Here is the challenge for the Lord of Butterflies.
