The rule that improves every run
There is no upgrade order worth following forever. Pay attention to why a run ended, then fix that problem. Damage and TNT strength handle stubborn blocks. Capacity gives you more time underground. Collection range cuts down the cleanup, while speed helps only when travel is eating a real chunk of the session. Save for another area once your power is ready for it.
That advice survives balance updates because it comes from the run you just played, not somebody else’s old price sheet.
Train with a test point
Training produces Damage, but training without testing can waste a session. Set a practical checkpoint: gain a visible amount, enter the target mine, and test one well-placed blast. If the wall still survives badly, return and train again. If it breaks cleanly, start earning.
After a Rebirth, use the same test method instead of trying to remember an exact old number. Permanent bonuses and balance changes can alter the amount you need.
Place for coverage, not spectacle
Scan the wall and floor before dropping a crate. The best normal placement sits close to several intact blocks that you can collect immediately afterward. Edge placements spend part of the blast on empty space. When you gain multi-TNT capacity, spread placements over separate clusters unless a high-durability target requires concentration.
Take a quick look, place the crate, light it, and collect before moving on. Dropping the next TNT while good loot is still behind you is how a fast run quietly turns into a wasteful one.
Match upgrades to visible symptoms
| Symptom | What to inspect | Practical choice |
|---|---|---|
| Repeated blasts barely open a route | Damage and TNT tier | Improve power first |
| The bag has room but TNT is gone | TNT capacity | Extend the run |
| Drops require awkward backtracking | Collection range | Improve pickup coverage |
| Long paths separate mine, shop, and sell | Speed | Reduce travel overhead |
| Current mine clears instantly | Next-area requirement | Save if the next mine is usable |
Before buying, compare the live cost with how often the problem occurs. A small range improvement used on every explosion can be more valuable than a costly power jump you do not yet need.
Sell before downtime begins
The right sell time is when continuing stops producing blocks efficiently. Return when your inventory is nearly full, your TNT supply is exhausted, or your current power cannot move the layer. A full bag is not the only signal; being unable to blast is equally decisive.
Plan the next purchase before you leave the mine. That turns the lobby stop into a quick sale-and-upgrade action instead of a long menu pause.
Use depth and rarity together
Deeper layers generally lead toward rarer blocks, but rarity does not excuse inefficient mining. If a rare or Secret target needs too many blasts, clear nearby profitable blocks and improve first. When a Secret spawn message appears, scan the active mine and deeper exposed paths quickly, but do not assume a fixed guaranteed location.
For normal farming, compare value per run rather than the largest single block. Several clean clusters often beat one slow prize.
Make pets serve the route
Egg Shards connect to eggs and pets. Open the current pet menu and compare the bonuses shown on each card. Equip for the bottleneck: clearing support when blocks resist you, income support when Cash growth is slow, or another clearly stated benefit when it improves the active route.
Rarity alone is not a decision. A lower-rarity pet with the right live bonus can fit your route better than a rarer pet aimed at a problem you do not have.
Prepare Rebirth instead of improvising it
Open the Rebirth panel before committing and read both sides of the trade: what resets and what persists. Then create a rebuild checklist covering training, the first profitable mine, core TNT, capacity, and area unlocks. Rebirth is faster when you already know the order back to your previous position.
Delay the reset if one nearby purchase unlocks a large earning increase. Take it when the permanent gain improves repeated future cycles and the rebuild time is acceptable.
Small habits that compound
- Center the camera on the intended block cluster before placement.
- Collect immediately after a blast while the crater is easy to read.
- Keep enough Cash flexibility to fix a new bottleneck.
- Test a new mine before assuming it is more profitable.
- Recheck shop, pet, and Rebirth text after updates.
- Use the mine deeper guide when route depth becomes the main goal.
FAQ
What is the best tip for faster progress?
Identify the exact reason your last run stopped, then spend on that bottleneck instead of following a fixed purchase list.
Should I stack all my TNT together?
Usually no. Spread crates across intact clusters for coverage; stack only when a durable target survives individual blasts.
When should I return to sell?
Return when inventory, TNT supply, or block durability prevents the run from producing value efficiently.
Are deeper blocks always worth chasing?
They trend toward rarer value, but a target is inefficient if your current power requires too many blasts. Upgrade and return.
How often should I check current stats?
Check shop cards, pet bonuses, and Rebirth terms whenever an update lands or a guide’s exact values differ from your game.
