Build a wall. Press start. Watch up to 200 zombies hunt for a way in!

ZOMBIE BLOCK DEFENSE is a bright, blocky wall-building tower defense puzzle. Build a wall around your hero, press Start, and watch the zombie horde hunt for a way in. Your wall plays out live: zombies chew through weak blocks, squeeze through gaps and swarm the corners. Did your defense hold?

HOW IT PLAYS
- Place blocks on the grid, tap Start and watch the wave.
- Zombies take the cheapest way in, so a smart layout beats a big one.
- From a handful of zombies to hordes of 200 from up to four sides.
- No-build squares, stronger blocks and new threats keep each level different.
- A level takes about a minute, ideal for short breaks.

50 LEVELS
Fight across a winding map of zones, each with its own look and twist. Replay levels to win a gold medal for using fewer blocks.

SPECIAL BLOCKS
Unlock spikes, bombs, ice, brain bait, pits, tesla coils and menders. Freeze the horde, drop zombies in a pit, chain-zap them, blow a hole in the line, lure them with a brain or mend your wall mid-wave.
