Depending on the concept, the basic versions of browser games can be used free of charge. Costs are only charged when additional functions are used. Browser games are divided into offline games and online games. Offline games do not require an active Internet connection. After activating the game on the browser, a single player can play the game. It is different with online games in which several or many players actively participate via the Internet.
As with other games, there are different cost models for use, which can be usage-dependent and range from subscription to purchase.
