Defense Mode
Hold the middle. Slimes attack your base from every direction.
In Defense Mode you protect a base in the middle of the screen. Slimes spawn from every direction (360°) and march straight at it at a steady speed. Pop them before they arrive.
The base
- The base starts with a shield.
- The first slime to reach the base breaks the shield. The screen flashes red.
- After a hit, the base is invulnerable for 1.5 seconds, so one cluster cannot finish you off.
- The next hit destroys the base and ends the run.
- Any slime that reaches the base counts as a hit. Slimes do not expire in this mode, so every slime must be popped.
- A Guard shield blocks base hits while it is active.
Waves
- Wave 1 sends 6 slimes. Each next wave adds 2 more.
- The delay between spawns starts at 1.2 s and shrinks by 0.02 s per wave, to a minimum of 0.25 s.
- Every 5th wave is a Surge: 1.5 times as many slimes at twice the spawn speed. The wave label turns red (“Wave 10 - SURGE!”).
- Clear every slime to finish a wave. A progress bar fills as you deal with each one.
- The background colour changes every 5 waves.
Full numbers are in the Defense wave table.

On PC, use Esc to pause.
Tips
- Chain-Reaction and Explosive slimes are your best friends: slimes bunch up as they converge on the base.
- Deal with Shield and Ghost slimes first, because they take longest.
- Frost and Guard are the best pets here. See Defense strategy.
