In Gorillas: Tiles Of The Unexpected we have to use the "mouse" or the "finger" to click on pairs of 2 or more to remove them from the grid. They have to be next to each other! For each match we collect bombs, which can be used later on when no more matches are available. The bombs remove one tile we click on. If one row is removed the other one will slide over. With this different logics we have to remove all tiles in every level.
