In 1909, tsar Nicholas II, Emperor of Russia commissioned Carl Faberge a finely decorated easter egg. The resulting piece of art carried a sophisticated surprise inside -- a finely crafted mechanical game. Furnished with colorful jewels, the game's mesmerizing patterns proved so addictive that Nicholas ordered the egg to be destroyed. To this day, the Faberge egg has never been found again. But, almost a century later, the original blueprints mysteriously showed up at an antique shop in the Rastro district of Madrid and got in the hands of a software developer, who made a faithful digital reproduction, restoring the old game to its former glory. The aim of the game is to control and place the falling blocks so that horizontal or diagonal combinations of at least three blocks of the same color appear. Once a combination is formed, it will disappear and any blocks above it will collapse. The sequence is repeated as long as new combinations are formed. A sequence of three collapses in a row is called a Trojka.
