Do you like chess? Now you can view your favorite chess games in a single application. All you need is our Chesser application and an internet connection. Then you can explore our chess database completely for free! Chesser is an easy viewer of chess games in pgn format. It needs no additional permissions and no access to your mobile phone data either. Everything is online and for free. We provide more than 900k chess games in pgn format. We have collected the most important games of the great chess grand masters and our database is still growing. There is a simple search tool to look for games where you can search according to chess player name, chess game year, place where the chess game was played, result, opening, etc. Some games have comments so you can see what the ideas, threats and motivations are behind the moves in each game. This is version 1 of our application. However, we are working on the next generation of Chesser in which we want to introduce more interesting features. Enjoy viewing your favorite chess games :)
