GameFi — a portmanteau of “game” and “finance” — involves blockchain games that offer economic incentives to play them, otherwise known as play-to-earn games. Typically, players can earn in-game rewards by completing tasks, battling other players or progressing through various game levels. Many of the play-to-earn games on the scene right now rely heavily on what game designers call a grinding mechanic, in which players have to spend lots of time doing repetitive tasks within a game to advance or unlock prizes — or, in this case, crypto tokens.
