GemTD Mobile

Players randomly create multiple gems in each level and use one of the gems as a defense tower to attack monsters, and the others turn into stones to block monsters. The monsters will advance along the designated waypoints one by one, and the player forms a maze through towers and stones to increase the path for the monsters to reach the base. The level ends when the monster is defeated or the final path is reached. There are a total of 50 levels in the challenge mode. After completing 50 levels, the game is won. After the game is won, you can continue to challenge the endless mode until the HP returns to zero.
