A clean first-run loop
- 1
Read the next body first
Identify the incoming body before you drag. The fuse punishes deciding after you have already started aiming.
- 2
Build nearby pairs
Try to place matching small bodies within reach of each other instead of scattering every tier across the disk.
- 3
Protect open lanes
Larger worlds need room to settle. Avoid sealing every edge with unrelated small bodies.
- 4
Use rescue items for recovery
Save fuse control, small-body cleanup, and field reset effects for boards that are genuinely failing.
What changes as score rises
The official description says the fuse gets shorter as your score climbs. That turns late runs into a recognition test: know where each tier belongs before the body appears.
The exact fuse times and score thresholds are not published. Any precise timer table would be guesswork, so this guide does not present one.
Strategy on this page is practical guidance inferred from the verified merge and fuse rules, not a developer-authored solution.
Frequently asked questions
What is the goal in Primordial Sea?
Merge identical bodies through the creation chain, from Cosmic Dust to a Water Planet, while keeping the gravity disk under control.
Why did my held piece explode?
A fuse runs while you aim. If it expires, the piece explodes and can scatter your stack.
Is there an endless mode?
Yes. The official feature list includes endless free play in addition to three difficulty stages.
