Wishlist on Steam ↗

Run a fireworks workshop with up to 3 friends. Every extra scoop makes the shell bigger and worth more - and brings the workshop closer to blowing up. One listens with the stethoscope, one steadies the shell, one holds the bucket. Light the fuses at night: a sky full of fireworks, or a crater.

ANSWERS FOR YOUR FIRST SESSION

Boom or Bloom gameplay guide and player questions

Steam edition · Researched Oct 31, 2026 · Guide updated Oct 31, 2026.

Source facts

How do I determine if a shell is about to explode?

Monitor the pressure gauge to see the red zone limit and use the stethoscope to identify the shell's thickness. If a shell begins smoking or shaking, it is actively reacting and the internal pressure continues to rise for a short duration.

Our guidance

What is a recommended approach for managing shell stability?

You might consider holding a shell steady while your friends add scoops to reduce shakiness. If a shell starts smoking, you can throw a bucket of water over it, though this will cause the shell to lose 30% of its total value.

Based on source 1.

Source facts

What happens if I seal a shell too close to its limit?

Sealing shells near their limit creates daredevil shells. While these score the most points at night, they carry significant risks, such as bursting prematurely, veering off course to hit a guest, or simply fizzling out entirely.
