AMazing TD – Maze TowerDefense is a competitive multiplayer tower defense game. Build mazes and defend them from monsters and other players. With a weekly or daily reset, the maps and the monsters are always different, so the game is always challenging and exciting.

You can play against the computer or other players in real-time PvP (Player vs. Player) and ELO (Elo ranking) games. If you’re feeling confident, you can even challenge your friends to a duel.

In the duel, you’ll face the opponent with the same skill level. To win, you’ll need to defeat more monsters or the opponent himself.

If you’re feeling less confident, you can play in the duel with the computer.

On the other hand, if you lose, you’ll get damage and your skill will decrease. This means that the lower your skill level, the more difficult it will be to defend your maze from attacks.
