Defense strategy

Your base survives one hit, then it is destroyed. Slimes march from all directions at a constant speed, so waves are about volume, not speed.

Key facts

• Slimes never expire. Every slime must be popped.
• Wave 5, 10, 15 and so on are Surge waves with 1.5× slimes at double spawn speed.
• You save a checkpoint every 5 waves.

See the Defense wave table.

Strategy

1. Pop from the outside in. Slimes far from the base are free to ignore for a moment, but never let one get close.
2. Save Explosive and Chain-Reaction slimes for bunching. Slimes converge toward the middle, so detonate when they are 2 or 3 deep.
3. Shield slimes first. They need two taps.
4. Ghost slimes only take hits when visible. Do not waste taps.
5. Prepare for Surge waves. Use Frost, Guard or Vortex when the label turns red.

After a hit

You have 1.5 seconds of invulnerability. Use it to clear the closest slimes.

Checkpoints

Beat wave 5 and your next run starts at wave 6. You can stack that progress safely. See Defense Mode.
