Block Tower Defense
Stop the bouncy blobs before they reach the castle.
Block Tower Defense is a friendly strategy game. A wobbly crowd of jelly Grumblobs is bouncing along the path to your castle, and only your towers can stop them.
Place towers next to the path: the Pebble Popper hits one blob at a time, the Frost Fan slows them down and the Bubble Blaster pops a whole group. When a blob has had enough it pops into sparkles and coins, which you spend on more towers and upgrades.
There are 15 levels across the Meadow, the Desert and Snowland. Keep all your hearts to earn three stars.
How to play
- Pick a level and look at the path the blobs will take.
- Tap a free tile next to the path and choose a tower.
- Start the wave and watch your towers pop the blobs.
- Spend your coins on new towers or tap a tower to upgrade it.
- Survive every wave to finish the level.

- Upgrading one tower is often better than building two weak ones.
- Armoured blobs need a few hits, so place towers early on the path.
