The old school tower defense game is back, as a play-to-earn based NFT blockchain game, Castle Defense. Now defend, attack and grow your territory with your NFT Castle.
Sponsors buy NFT Castles that can be used by players who contribute XP to the castle while playing the game, thereby making it stronger and increasing the value of the NFT Castle. The sponsor can also sell the upgraded castle on the NFT Castle Market and earn a profit on sales.
See www.castledefense.io for more details.
You can play Castle Defense by clicking this link on any browser of your PC, tablet or your mobile ( both on Android or Apple mobile phone). It is free-to-play game. You are not required to buy NFT in order to play and earn XP in this game.
