Casual strategy

Casual Mode is endless. The numbers grow every wave, so your goal is to keep three hearts for as long as possible.

The numbers

• Wave 10 has 22 slimes, wave 20 has 42, wave 30 has 62.
• The spawn delay shrinks until wave 36, when it reaches 0.15 s.
• Each good slime that expires costs a heart.

See the Casual wave table.

Strategy

1. Clear the oldest slime first. Every slime lives 5 seconds.
2. Priority list: Heart (when hurt) → Shield (needs two taps, start early) → everything else.
3. Treat Ghost as a timing puzzle. Tap when it is bright.
4. Mirror and Blind slimes are a nuisance, not a danger. Pop them last, or when the screen is quiet.
5. Use Slow-Mo to reset when too many slimes are on screen.

Pets

• Guard every 16 seconds gives you free breathing room.
• Vortex is a screen wipe every 29 seconds.
• Bones rescues 30% of expiring slimes.
