Your goal is to find three stones that make a set! Three stones form a set, if for each of the four properties (shape, color, style, and number of the painted sign) either all three are of the same kind or all three are of different kinds. • Too difficult? In the easy mode, the style property is skipped. • Too easy? In the hard mode, there is an additional background property and you play on 5*5 stones. • Can’t find a set? Don’t worry! In the beginning it is very challenging to find one - so take your time! There always is a set! And there is a hint button… ☺ Each set found is a plus point, every mistake a minus point. Find as many sets as possible as fast as you can! The faster you score points, the more likely you will discover a mammoth and other paintings on the wall. Features • tutorial (with infinite number of examples) • customizable colors • layout for portrait and landscape mode • three levels of difficulty • achievements and leaderboards (optional, with Google Play Game Services) • multiplayer: up to four players can play at a single device together in two different modes (alternately vs. time or simultaneously) Free of ads. Your feedback is welcome. Have fun!
