Upgrade when the drill is your current bottleneck
Use the cash from hatched animals to upgrade your drill when digging is what slows your next trip. First, bring an egg home and hatch it. Then check the upgrade card for its current price and effect. Choose from the options you can see in your session, rather than following an assumed tier order.
A useful upgrade solves a problem you can name. Perhaps your current drill cannot make the progress you want, or an option clearly helps your next search. Before your first full egg trip, that decision is harder to make. Learn where the Farm shows animal income so you know how much cash you have and what the purchase is meant to change.
Compare the live options
Drilling raises POWER, and deeper digging can lead to rarer eggs. Check the live upgrade card to see what a particular purchase does. If it shows a stat increase, note the number. If it shows only a name, test the drill after buying instead of guessing a multiplier.
| Question before buying | Why it matters |
|---|---|
| What is the current cash cost? | Prices can change; decide using the amount shown in your session. |
| What effect does the game display? | Different upgrades may address different limitations. |
| What stopped my last dig? | A purchase should solve the obstacle you actually met. |
| Can I still support the Farm loop? | Cash may also be useful for Farm growth. |
| What can I compare afterward? | A short drilling test shows whether the purchase helped. |
If you have several choices, compare them against the same goal. The option at the end of a list is not automatically best, and the cheapest one is not automatically efficient. Read the current prices and effects before committing your cash.
Test one change at a time
Before buying, note your POWER and how the drill handles a short stretch of familiar ground. Buy an option whose displayed effect fits your goal, then try a similar stretch again. Check POWER and your digging progress. You only need a useful before-and-after comparison.
POWER already rises when you drill. If you compare numbers hours apart, you cannot tell how much of the gain came from the upgrade. Use similar stretches instead. When a card promises a different effect, judge that effect; not every drill purchase has to raise POWER directly.
Once the drill is ready, dig down and look for an egg. Deeper digging can lead to rarer eggs, but do not expect a named find or guaranteed rarity from one upgrade. Bring the egg back to your Farm, hatch it, and use the animal’s income for later purchases.
Do not forget the Farm side
You can spend animal earnings on Farm growth too. If the Farm is holding you back, check its options before buying another drill change. There is no need to split spending by a fixed ratio. Compare what each purchase unlocks for your next trip.
Animals also earn cash while you are offline. When you return, check your balance and the earnings display before comparing upgrades again. You might now afford an option that was out of reach, but its current price and effect still determine whether it helps.
