The basic loop every new player needs to know
Step
The whole game runs on one cycle. You place TNT on the ground, set it off to blow up the terrain around it, then grab the ores that pop out of the crater. Those ores fuel everything else — new TNT types, better explosives, and deeper access. The deeper you go, the rarer the ores you find.
- Place your TNT position it on the ground where you want to dig.
- Trigger the explosion ignite the TNT to destroy the surrounding terrain.
- Collect the ores pick up everything that appears in the blast zone before moving on.

The TNT unlock ladder
Tips
There are more than twenty TNT types to work through, each with its own explosion effect. Dirt TNT is the first unlock and the one that gets real digging started — earning it also awards the Unlock Dirt TNT badge. From there the ladder runs through types like Ice, Mushroom, Fling, Lightning, Gold, Slime, Steel, Ball, Steampunk, Rainbow, Watermelon, Glitter, Diamond, Chocolate, Lava, and Glitch before reaching the heavy hitters at the top.
- Dirt TNT is your first target — unlocking it earns a badge and marks the real start of the game.
- Ice TNT produces giant ice spikes; Fling TNT throws everything in its blast radius.
- Slime TNT spreads sticky slime across the ground, while Steampunk TNT shoots out gears.
- Nuke TNT arrives in the later stages and delivers an atomic-scale explosion.
- Moon TNT, Galaxy TNT, and Blackhole TNT are the endgame targets — Blackhole TNT is among the last unlockable types.
- Every unlock awards its own badge, so the badge list doubles as a progress tracker.
Depth milestones and what they unlock
Check
Reaching Layer 1 is the first depth milestone the game marks with a badge, and it signals that you are past the surface and into basic stone. The goal from there is to keep pushing down, because deeper layers produce rarer ores. The final destination is the earth's core.
- Reach Layer 1 the first underground milestone, marked by the Reach Layer 1! badge.
- Collect rarer ores they appear the deeper you dig.
- Reach the earth's core the final destination and the game's main objective.
Free-to-play progression
Tips
Every TNT type in the game can be unlocked using in-game currency alone, so reaching the core without spending Robux is entirely possible. Rare ores accumulate steadily as long as you keep digging, and the gap between free and paying players closes with time.
- All TNT types are purchasable with in-game currency — no Robux required.
- Rare ores build up the deeper you dig.
- If the next TNT tier is out of reach, put your currency into upgrading what you already have.
Common sticking points
Warn
The fix is almost always to unlock the next TNT tier. If the next tier is too expensive, upgrade the TNT you already own.

Common questions
FAQHow do I earn money in this game?
You earn income by collecting ores after each explosion. Deeper layers contain higher-value ores, so your earnings grow as you progress further toward the core.
What is the actual goal of the game?
The main objective is to reach the earth's core. Along the way, unlocking every TNT type — with Blackhole TNT as the top of the ladder — is a goal in itself, and each unlock earns you a badge.
What should I do when progress feels stuck?
Try unlocking the next TNT tier. If that tier is out of reach, upgrade the TNT you already own.
In what order should I unlock TNT types?
Dirt TNT is the first unlock and the right starting target. After that, work through the ladder in sequence. Blackhole TNT sits near the very end of the ladder.
