There are more than ten different, small, animated monsters in the game who shuffle their feet and look around trying to avoid being noticed. They are hiding, alone or in groups, from the player who is a simple stick figure in the lower left of the screen. Played in portrait orientation, the monsters take shelter on a never-repeating assortment of bizarre structures, on a gameboard filled with obstacles and barriers that make for some very complex ricochets. Depending upon the composition of the item, it will emit a particular sound when hit by one or more gemstones bouncing off surfaces at various speeds. The object of the game is to clear the board of all the monsters, earning one, two, or three stars depending upon the number of gems required. When all the monsters are gone, the player moves to the next stage.

Besides the web of angles in each puzzle, each gemstone has a special capability, and players can select the gem they want to fire (only the launch angle, not velocity, can be controlled with a touch gesture) from those available at that stage. Pinkish violet Amethysts behave normally, bouncing predictably off objects with the angles equal before and after collision. The deep green Emerald also behaves normally, until the player taps the screen while it is moving and it splits into two Amethysts, capable of twice the destruction. The blood red Ruby is similar, but explodes, rather than splits, when the screen is touched.

The gameplay is always highly dynamic with very creative puzzles, projectiles, interactions, and strategies for winning. The stylized, black and white graphics and animation establish a film noir mood, while the shooting gems and motion trails show up in high contrast.
