Shariki
Shariki is a puzzle video game written in 1994 for MS-DOS by Russian developer Eugene Alemzhin. The goal of the game is to gain progressively higher scores by matching three or more balls of the same color in a line, by swapping adjacent balls. Each swap must result in a match. Matched balls are then removed, and new ones drop from the top to fill the gaps. The game is over when no more matches are possible in the game field.
