Blookets Tower Defense 2 is a remake of their first one. In this game mode, the player answers questions, builds towers, and designs their defence to protect them from waves of evil blooks. It gets more difficult as you clear further rounds by adding more and stronger enemies.
Towers are Blooks that can be bought and placed in spaces with no track or object already occupying that space. Each tower has a price and 4 upgrades. The first tier of upgrades gives the tower a wooden base. The next tier of upgrades gives the tower a stone base, as well as granting a small appearance change to the tower itself. The third tier of upgrades gives the tower a golden base. The final upgrade gives the tower a blue diamond base as well as another appearance change. Towers can also be sold depending on their worth.
