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.
